Clementine DeVore spent 10 years trapped in a cellar, pinned down by willow roots, silenced and forgotten. Now she's out and determined to uncover who put her in that cellar and why. When Clementine was a child, dangerous and inexplicable things started happening in New South Bend. The townsfolk blamed the fiendish people out in the Willows and burned their homes to the ground. But magic kept Clementine alive, walled up in the cellar for 10 years, until a boy named Fisher set her free.

Back in the world, Clementine sets out to discover what happened all those years ago. But the truth gets muddled in her dangerous attraction to Fisher, the politics of New South Bend, and the Hollow, a fickle and terrifying place that seems increasingly temperamental ever since Clementine reemerged.
