Frost murmured, 'Two, four, sixteen, two hundred and fifty-six...' She grabbed papers and started s.c.r.e.w.i.n.g them up. 'It's my fault! I brought it on us! I renounce it!'

I said, 'Why not have some breakfast?'

'Eat? I've no time! The milk in my coffee is all the breakfast I need!'

I sat down on the edge of the table and she indicated her fortification of books and tool boxes. 'This is my office. I am in charge of the dam.'

'Of course,' I said soothingly.

'Even if everything else fails, my project won't!'

'Cool it.'

She put the handfuls of paper down slowly. 'Oh, Jant. Why are we engineers always hoist with our own blocks?'

'We need you. You're the smartest of us,' I said.

'It gets thee nowhere. Being smart just gets people killed.' She poured another coffee.

'Maybe you should stop drinking that,' I added.

'It's just a cup of coffee.'

'It's not a cup of coffee, it's a state of mind.'

Doubt masked Lightning's usually stately face. He said, 'I don't know why the Insects have changed...Rayne once suggested that they bred underground or in cells behind the Wall. Why have we never seen a flight before?'

I said, 'I told you they were coming from the s.h.i.+ft.'

'Shut up about your drug fantasies!'

'Don't you remember the bridge?' I asked. 'Where do you think it led?'

Lightning blanked me out, and said, 'Maybe there are lakes out of view in the north.'

I sighed. 'If you want. But I circled their flight and I saw them coupling in a big, slimy orgy up there.'

Frost squeezed her eyes shut. Her body jerked upright, rigid in a long shudder. In a second she was back. 'A...another white flash. It's the pressure. Bad tension. II didn't know this would happen. How could I?'

Lightning said, 'We can't be sure'

'Oh yes,' I said. 'I'm sure.' The sights I had seen in the Somatopolis began to make sense: the obscure shape swimming in the pool, and how the water that had spouted through from Vista had triggered the Insects' instinct to breed.

I said, 'They're dropping food in the lake. The Wall is not just their means of protecting the Paperlands but also a way to store food.'

'Food?' Lightning grimaced. 'Why?'

'Because whatever comes out of those eggs will want to eat.'

Frost buried her head in her hands and started murmuring, 'I only wanted to be immortal because of Zaza...Two hundred and fifty-six; two hundred and sixty-five thousand, five hundred and thirty-six; four billion, two hundred and ninety-four million'

'Please stop doing that,' said Lightning.

I wondered how to help Frost. Asking her to relax would be like trying to convince a shark to stop swimming. If they stop, they drown, so I'm told. She habitually imposes so much stress on herself that this additional stress was more than she could cope with. The very qualities that had helped her gain immortalityremarkable self-discipline and a drive to work herself to the bonewere now impediments.

She is addicted to work and buries herself in it so deeply she's surprised when her actions affect anyone else. Let me give her a task, a purpose, another dose of work to calm her mind.

I picked up a sc.r.a.p from the tide of paper on her desk, folded it into a glider and threw it past her. She looked up resentfully, selected another sheet and made a glider of far better design. She creased the edge of one wing and tossed it. It described a circle around me, turned on its side and flew back to her.

I said, 'Do you know that water is running down the spillway?'

'Ha! A little overtopping; I'd expect it to be displaced by all that detritus. The culvert is adequate.' She sobbed and wiped her nose.

Lightning sighed, looking at the mortals lingering just out of earshot awaiting our command. 'Try to put a better front on for the Zascai.'

'She's in shock,' I said.

'We're all in shock.' Lightning added, 'There are not so many today. The flight could be dying down of its own accord.'

'I hope so,' I said.

Frost began to stutter, 'D-don't you see? That's the point. My lake affected all the Insects in in in the area. When they've all...mated...the flight w-will stop. Then what? Then what?'

Now did not seem to be the right time to tell her and Lightning about the death of the Somatopolis. The Vermiform had implied that Insects don't lay eggs in sea water. I asked, 'Can we make the lake saline?'

Frost's arms tensed. 'W-we don't have enough s-salt here.'

'Well, order some up.'

Lightning shook his head. 'Not a hope. How would you take it to the lake? There are too many Insects running free outside. With thousands over such an open area, they would slaughter us even if we had three times the number of troops.'

A commotion in the doorway interrupted us. Wrenn entered the hall, in full armour, dragging an Insect by its two antennae bundled together in one gauntleted hand. He had hacked off all its legs at the first joint, leaving stumps. Its antlike body squirmed, bending at the neck and waist, and it rotated from side to side as he pulled it over the straw-strewn floor to us.

He had caught it before it detached its wings. The long, hyaline membranes surrounded it completely, shredded into ribbons on one side, rattling and clattering together. It reared up its front femurs threateningly and yellow paste oozed out of the severed joints.

Frost stood up. 'Serein Wrenn Culmish, that is absolutely disgusting. Take it outside!'

'Morning, all. Think of it as one less Insect. I want to show you something.' He let go of the antennae and the Insect rocked on its back until it rolled the right way up. It was constantly trying to get to its feet, regardless of the fact that it didn't have any. The loss of a leg or mandible isn't a serious injury for an Insect because it can regenerate them in subsequent moults. This one was missing all six legs but it was still wriggling. It squirmed around and grabbed Wrenn's ankle.

He drew his broadsword with a flourish. As its jaws closed on the greave plate he swept its head off, leaving it dangling from his leg.

Its body slowly stopped moving. Wrenn kicked his foot free, and the head rolled to rest, compound eyes downward. 'I picked this one up on the road. Do you see it's fatter than usual?' He poked its abdomen with the tip of his sword. Pressing with both hands on the hilt, he punctured the softer sclerites under its abdomen at the waist and sliced it open to the tail. He turned his blade to widen the cut and a ma.s.s of white capsules the size of my palm suspended in clear jelly splodged out.

'Eggs. Lots of them. Do you see?' He stirred them with his sword point, cutting their cuticles, whereupon they leaked a milky liquid.

I slipped my hand into the cold, gelatinous sp.a.w.n, picked up one egg and squeezed it. It was the size of a tennis ball and very slimy, with a tough, sclerotic skin. It slipped between my fingers like a bar of soap, and bounced on the floor.

'Ugh,' said Frost.

'Sorry.'

'Thank you, Wrenn,' Lightning said. 'No less than your usual brilliance.'

'So why do they drop their wings off when they could keep flying and attacking us?'

'They're working on instinct,' I told him. 'They're interested in the lake. It's just coincidence that we're here at all.'

'But why fly? Why do they have to fly to s.h.a.g?'

'Ask it,' I said.

Wrenn took the point. 'Fair enough.'

He sat down on a bench end, removed his helmet and padded cap and ruffled his flattened hair to make the spikes stick up. He called to Tornado, 'It's your s.h.i.+ft, Tawny. I've been at it since five. Give me half an hour for breakfast then I'll come back out.'

Tornado picked up the Insect by the tip of its abdomen and dragged it, still dripping transparent gel, out of the hall.

Frost had knelt down and was counting the eggs, picking them up with gluey strands and piling them on one side. 'There are upwards of a hundred in here. Tens of thousands of Insects are laying. If they all hatch, there'll be millions of offspring in my lake...'

She brushed her hair back, leaving a trail of slime stuck to it, sat on her heels and looked at us, wide-eyed. 'I have to drain the lakeas quickly as possible.'

'How long will it take?' I said.

'I expected it to take days. I can't just reel the gate wide open; it would flood everything from here to Summerday. The breakwave would be...well, maximum outflow could easily wash the levee away, and then...I don't like to speculate.'

'How fast can you open the gate safely? What do you need? Tell us, so we can make plans.'

She jumped up and dashed to her desk. She whipped a sheet of paper towards her, grabbed two pencils, shoved one behind her ear and poised the other. 'If Q is the flow rate and dt is the time...Hum! Could the debris block the gate? No, its compressive stress is tissue to that force of water...You there! Yes, you. Bring me some more coffee! Where's my foreman? Asleep? Why? We have work to do! Oh, if Zaza were here we could do this in a couple of days!'

Lightning and I backed off. 'Thank you,' he said gratefully.

'I'm just trying to keep her occupied. We don't have sufficient troops to reach the winch tower anyway.'

He nodded. 'I know. We're stranded here, Jant, for now. But at least we're stranded with the largest store of arrows in western Lowespa.s.s.'

I noticed Kestrel Altergate at the far end of the room, trying to help a field surgeon without actually touching his patient. 'Just make sure Frost sleeps at some point, and keep those b.l.o.o.d.y reporters away from her.'

One of Lightning's wardens called from the spiral stairs. Lightning raised a hand in acknowledgement and said, 'I have to organise the archers on the towers. Please bring us some instruction from the Emperor.'

'I will.'

'I hope San knows what to do, because I fear I don't...Jant, did you find Cyan in Hacilith?'

'Er. Yes.'

'Wonderful! Well?' Lightning glanced to the Zascai clamouring for his attention. The bolder ones were beginning to approach. 'Is she safe?'

'She's safe now,' I said.

'Now? She wasn't safe before?'

'She was safe before and she's safe now.' But not during the time in between, I thought. Lightning gave me an urgent look, but I met his gaze. 'Rayne is bringing her here. They'll arrive in a couple of days.'

'Good. Thank you, Jant...' I could see Lightning wanted to ask me more but the Zascai were waiting. He fidgeted with the scar on his palm, then he nodded and went back to issuing commands.

Wrenn beckoned to me. 'When you see the Emperor, tell him that all our fyrd are knackered and scared stiff. The Cook said that he'll try to resume the wagon train, with extra outriders for protection, or we'll soon run out of food. I don't want to have to chew gum and tighten my belt until new supplies arrive.'

Wrenn pressed the clips to release his plates with a click; gorget, breastplate, faulds, and placed them on the floor. He was so hot his feathers stood up like needles on a pine branch, to let the heat escape. A few detached ones floated down. Wings don't perspire, but everywhere else his unders.h.i.+rt had brown tide marks and with the sweat of his latest exertion it stank.

He said, 'These clips don't last long. I have to keep threading on new ones. G.o.d, that's better. I feel much lighter now.'

His armour was state of the art, top of the range. I cast an envious eye over it. 'Nice gear.'

'Isn't it? Check out Sanguin.' He pa.s.sed me his broadsword.

'Very nice.'

'You can see the temper line and everything.'

I tilted the blade to see its etched arabesques and the name in a flowing Awian script.

Wrenn took his helmet on his knee and picked at the lining, then undid the finger-screws that held its bedraggled crest in place. He slid the crest out of its runners and began to wipe mud off it with his sleeve. 'It's a quagmire out there. And my arms are covered in bruises from lugging those f.u.c.king s.h.i.+elds.' He looked at my bandages. 'What happened to you?'

'I crash-landed.'

'Did you? Armour, Jant; get yourself some of this.'

'I can't fly in harness.'

'Wear something on your arms at least.' He grinned. 'What do you think you are, b.l.o.o.d.y immortal?'

I picked up one of his mirror-finish arm plates from the floor and turned it over. Its canvas straps were hidden underneath it and woven through with steel wire resistant to Insect jaws. The straps had metal spring clipsthey could be unfastened in a second if something did go wrong, and they were all easily reachable. Wrenn could don full harness in minutes.

He nodded at it. 'You should ask Sleat to make you some. It's much better than that old c.r.a.p scale you wear.'

'Show me,' I said.

He took off a greave and ran his finger inside it. 'Well, it's lightweight. Feel that. My breast and back plates are thinner than the ones for my arms and legs. Chain mail strips sit under every jointelbows, waist, kneesthey don't add much weight but no claw is going to find its way in there. And see the little holes?' He ran his finger along a line of perforations. 'They make it lighter still, but they're to let the air breathe. It doesn't collect sweat and rust and I can wear it all day without overheating. Not like old lancers' armour.'

It was the highest-quality steel with the sunburst inlaid in orpiment yellow. I ran my thumb over the smooth embossing and Wrenn chuckled. 'Decoration won't save your life. Look hereall the plates are straight-edged and tapered. Mandibles won't find purchase on that. There's deep fluting along every plateno jaws will be strong enough to crush that much reinforcement. Sleat's proved it in trials. Best of all, there are no small pieces for the b.a.s.t.a.r.ds to grabthe elbow couters are attached to the vambraces and the besagews aren't discs hanging loose, they're part of the breastplate, see?'

'Is this Morenzian?' All human armour was adaptable to Awians these days but sometimes the added pieces were unreliable.

'Sleat extended the pauldrons for me and I tuck my wings under them. He can do the same for you. He took my measurements when I joined the Circle. He made exactly what I wanted.'

'Sleat custom-forges armour for every new Eszai,' I said.

'He made me a whole garniture suite.'
