In the seaside town of Kinlough, on Ireland’s west coast, three old friends are thrown together for the first time in years.

But by midnight, Rhys will be floating dead in the freezing waters of the lake. On New Year's Day, Ffion Morgan has a village full of suspects.

When I think about what I actually did, I feel somewhat sad that nobody will ever know about the complex operation that I undertook. Getting away with it is highly preferable, of course, but perhaps when I’m long gone, someone will open an old safe and find this confession. The public would reel. After all, almost nobody else in the world can possibly understand how someone, by the tender age of twenty-eight, can have calmly killed six members of her family. And then happily got on with the rest of her life, never to regret a thing.

A landslide has closed the Korowai Pass on New Zealand’s South Island, cutting off the town of Thorndike and leaving a sizable farm abandoned. The disaster presents an opportunity for Birnam Wood, an undeclared, unregulated, sometimes-criminal, sometimes-philanthropic guerrilla gardening collective that plants crops wherever no one will notice. For years, the group has struggled to break even. To occupy the farm at Thorndike would mean a shot at solvency at last. But the enigmatic American billionaire Robert Lemoine also has an interest in the place.

Isabel Gibson has all but perfected the art of forgetting. She’s a New Yorker now, with nothing left to tie her to Brinkley’s Island, Maine. Her parents are gone, the family bookstore is all but bankrupt, and her sister, Sophie, will probably never speak to her again. But when a mysterious letter arrives in her mailbox, Isabel feels herself drawn to the past. After years of fighting for her independence, she dreads the thought of going back to the island.

Molly Black has disappeared. She's been a bit flighty since her parents died (sure, hadn't she run off with a tree surgeon that time?) but this time, or so says her hastily written leaving note, she's gone for good. That's why the whole Black clan—from Granny perched on the printer all the way through to Killian on Zoom from Sydney—is huddled together in the back room of Uncle John's semi-D in the Dublin suburbs, arguing over what to do.
