Pearl doesn't know how she's ended up in the river - the same messy, cacophonous river in the same rain-soaked valley she'd been stuck in for years. Or why, for that matter, she'd been stupid enough to fall down those rickety stairs.
Ada, Pearl's daughter, doesn't know how she's ended up back in the house she left thirteen years ago. With her daughter Pepper, she starts to sort through Pearl's things, clearing the house so she can leave and not look back. As the first frosts of autumn herald the coming of a long winter, and Pepper and Ada find themselves irresistibly entangled with the life of the valley, each will discover the ways that places can take root inside us and bind us together.
