Bree and Eve share one body, but they are two girls as different as night and day. Eve is secretive and unpredictable. Bree is an open book to her other half. Eve prefers to handle conflict with violence. Bree can barely stand the sight of blood. But one goal unites them: their desire to be safe from the Trackers who hunt their kind. And for years, they wander from city to city, in search of the one who will free them forever.
When Bree meets Isadric, a young man with dangerous connections and a penchant for taking in strays, including her, she finds it hard to move on. But the secret she hides risks doing more than driving them apart. It might just turn them into enemies.
There’s also Tristan, a boy with secrets of his own, secrets that help Eve. As Eve’s strength grows and Bree struggles to keep up, the two girls are pitted against each other in a battle over the body they share. And only one of them will make it out alive.
