Bree and Eve share one body, but they are two girls as different as day and night. Eve is secretive and unpredictable. Bree withholds nothing from her other half. Eve prefers to create resolution through violence. Bree can barely stand the sight of blood. But one goal unites them: desire to be safe from the Trackers who hunt their kind. And for years they wander from city to city, in search of freedom and the little brother Bree believes is still alive.
When Bree meets Daniel, 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 her 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 with the Trackers closer than ever to finding them, there’s a chance neither of them will make it out alive.
