Scotland and joined a group of green radicals who’d been building a self-sufficient settlement on a trio of ancient oil rigs in the Firth of Forth. But they’d become compromised too, according to Julia, so she’d left them and taken up with Lucas’s father (Lucas knew almost nothing about him—his mother said that the past was the past, that she was all that counted in his life because she had given birth to him and raised and taught him), and they’d lived the gypsy life for a few years until she’d split up with him and, pregnant with her son, had settled in a smallholding in Norfolk, living off the grid, supported by a small legacy left to her by one of her devoted supporters from the glory days of the anti-alien protests.
When she’d first moved there, the coast had been more than ten kilometers to the east, but a steady rise in sea level had flooded the northern and eastern coasts of Britain and Europe. East Anglia had been sliced in two by levees built to protect precious farmland from the encroaching sea, and most people caught on the wrong side had taken resettlement grants and moved on. But Julia had stayed put. She’d paid a contractor to extend a small rise, all that was left of her smallholding, with rubble from a wrecked twentieth-century housing estate, and made her home on the resulting island. It had once been much larger, and a succession of people had camped there, attracted by her kudos, driven away after a few weeks or a few months by her scorn and impatience. Then most of Greenland’s remaining icecap collapsed into the Arctic Ocean, sending a surge of water across the North Sea.
Lucas had only been six, but he still remembered everything about that day. The water had risen past the high tide mark that afternoon and had kept rising. At first it had been fun to mark the stealthy progress of the water with a series of sticks driven into the ground, but by evening it was clear that it was not going to stop anytime soon, and then in a sudden smooth rush it rose more than a hundred centimeters, flooding the vegetable plots and lapping at the timber baulks on which the caravan rested. All that evening, Julia had moved their possessions out of the caravan, with Lucas trotting to and fro at her heels, helping her as best he could until, some time after midnight, she’d given up and they’d fallen asleep under a tent rigged from chairs and a blanket. And had woken to discover that their island had shrunk to half its previous size, and the caravan had floated off and lay canted and half-drowned in muddy water littered with every kind of debris.
Julia had bought a replacement caravan and set it on the highest point of what was left of the island, and despite ineffectual attempts to remove them by various local government officials, she and Lucas had stayed on. She’d taught him the basics of numeracy and literacy, and the long and intricate secret history of the world, and he’d learned field- and wood- and watercraft from their neighbors. He snared rabbits and mink in the woods that ran alongside the levee, foraged for hedgerow fruits and edible weeds and fungi, bagged squirrels with small stones shot from his catapult. He grubbed mussels from the rusting car-reef that protected the seaward side of the levee, set wicker traps for eels and trotlines for mitten crabs. He fished for mackerel and dogfish and weaverfish on the wide brown waters of the Flood. When he could, he worked shifts on the shrimp farm owned by Damian’s father, or on the market gardens, farms, and willow and bamboo plantations on the other side of the levee.
In spring, he watched long vees of geese fly north above the floodwater that stretched out to the horizon. In autumn, he watched them fly south.
He’d inherited a great deal of his mother’s restlessness and fierce independence, but although he longed to strike out beyond his little world, he didn’t know how to begin. And besides, he had to look after Julia. She would never admit it, but she depended on him, utterly.
She said now, dismissing his offer to take her along, “You know I have too much to do here. The day is never long enough. There is something you can do for me, though. Take my phone with you.”
“Damian says phones don’t work around the dragon.”
“I’m sure it will work fine. Take some pictures of that thing. As many as you can. I’ll write up your story when you come back, and pictures will help attract traffic.”
“Okay.”
Lucas knew that there was no point in arguing. Besides, his mother’s phone was an ancient model that predated the Spasm: it lacked any kind of cloud connectivity and was as dumb as a box of rocks. As long as he only used it to take pictures, it wouldn’t compromise his idea of an off-the-grid adventure.
His mother smiled. “ ‘ET go home.’”
“ ‘ET go home’?”
“We put that up everywhere, back in the day. We put it on the main runway of Luton Airport, in letters twenty meters tall. Also dug trenches in the shape of the words up on the South Downs and filled them with diesel fuel and set them alight. You could see it from space. Let the unhuman know that they were not welcome here. That we did not need them. Check the toolbox. I’m sure there’s a rattle can in there. Take it along, just in case.”
“I’ll take my catapult, in case I spot any ducks. I’ll try to be back before it gets dark. If I don’t, there are MREs in the store cupboard. And I picked some tomatoes and carrots.”
“ ‘ET go home,’” his mother said. “Don’t forget that. And be careful, in that little boat.”
Lucas had started to build his sailboat late last summer, and had worked at it all through the winter. It was just four meters from bow to stern, its plywood hull glued with epoxy and braced with ribs shaped from branches of a young poplar tree that had fallen in the autumn gales. He’d used an adze and a homemade plane to fashion the mast and boom from the poplar’s trunk, knocked up the knees, gunwale, outboard support, and bow cap from oak, persuaded Ritchy, the shrimp farm’s foreman, to print off the cleats, oarlocks, bow eye and grommets for lacing the sails on the farm’s maker. Ritchy had given him some half-empty tins of blue paint and varnish to seal the hull, and he’d bought a set of secondhand laminate sails from the shipyard in Halvergate, and spliced the halyards and sheet from scrap lengths of rope.
He loved his boat more than he was ready to admit to himself. That spring he’d tacked back and forth beyond the shrimp farm, had sailed north to along the coast to Halvergate and Acle, and south and west around Reedham Point as far as Brundall, and had crossed the channel of the river and navigated the mazy mudflats to Chedgrave. If the sea dragon was stuck where Damian said it was, he’d have to travel farther than ever before, navigating uncharted and ever-shifting sand and mud banks, dodging clippers and barge strings in the shipping channel. But Lucas reckoned he had the measure of his little boat now, and it was a fine day and a steady wind blowing from the west drove them straight along, with the jib cocked as far as it would go in the stay and the mainsail bellying full and the boat heeling sharply as it ploughed a white furrow in the light chop.
At first, all Lucas had to do was sit in the stern with the tiller snug in his right armpit and the main sheet coiled loosely in his left hand, and keep a straight course north past the pens and catwalks of the shrimp farm. Damian sat beside him, leaning out to port to counterbalance the boat’s tilt, his left hand keeping the jib sheet taut, his right holding a plastic cup he would now and then use to scoop water from the bottom of the boat and fling in a sparkling arc that was caught and twisted by the wind.
The sun stood high in a tall blue sky empty of cloud save for a thin rim at the horizon to the northeast. Fret, most likely, mist forming where moisture condensed out of air that had cooled as it passed over the sea. But the fret was kilometers away, and all around sunlight flashed from every wave top and burned on the white sails and beat down on the two boys. Damian’s face and bare torso shone with sunblock; although Lucas was about as dark as he got, he’d rubbed sunblock on his face too, and tied his straw hat under his chin and put on a shirt that flapped about his chest. The tiller juddered minutely and constantly as the boat slapped through an endless succession of catspaw waves and Lucas measured the flex of the sail by the tug of the sheet wrapped around his left hand, kept an eye on the foxtail streamer that flew from the top of the mast. Judging by landmarks on the levee that ran along the shore to port, they were making around fifteen kilometers per hour, about as fast as Lucas had ever gotten out of his boat, and he and Damian grinned at each other and squinted off into the glare of the sunstruck water, happy and exhilarated to be skimming across the face of the Flood, two bold adventurers off to confront a monster.
“We’ll be there in an hour easy,” Damian said.
“A bit less than two, maybe. As long as the fret stays where it is.”
“The sun’ll burn it off.”
“Hasn’t managed it yet.”
“Don’t let your natural caution spoil a perfect day.”
Lucas swung wide of a raft of bubbleweed that glistened like a slick of fresh blood in the sun. Some called it Martian weed, though it had nothing to do with any of the aliens; it was an engineered species designed to mop up nitrogen and phosphorous released by drowned farmland, prospering beyond all measure or control.
Dead ahead, a long line of whitecaps marked the reef of the old railway embankment. Lucas swung the tiller into the wind and he and Damian ducked as the boom swung across and the boat gybed around. The sails slackened, then filled with wind again as the boat turned toward one of the gaps blown in the embankment, cutting
