A chilling and heartbreaking story of a young girl's loss and resilience by Peter Heller, the best-selling author of The Dog Stars, The Painter, and The River.

In this riveting tale of looming apocalypse, Pup is living off the grid for the summer with her parents on an island off the coast of Maine, when all three of them face the hardest decisions of their lives. Across the water one night they can see homes burning and hear gunfire. Pup and her parents, with their goat and chickens and garden and their dog, Opey, have no contact with the mainland, except for boat runs into town. When their friends, two women biologists living on a tiny island two miles away, bring them news of the civil unrest up and down the coast and talk of secession, Pup's father agrees to go into town with the women in their boat to check on things. It's a fateful decision that will force Pup to make choices she could never have imagined, and that will alter the world for everyone.
