All Eve Ellaway wants is to escape to college, start a life of her own, and finally sever the connection to her twin sister Gen who disappeared when they were babies. Because while the rest of the world moved on from the kidnapping, Gen's still very much alive at home.

Most families would grieve their missing child. Some families might create a shrine for their lost daughter. But the Ellaways are not most families.

Every night, Eve pretends to be Gen to protect her mother's delicate grasp on reality — dividing her life, her stories, and her dreams so there's enough for two sisters. Eve's forced to maintain her father's lie to ease his guilt over Gen's disappearance, but is she sacrificing the last threads of her identity and any hope for a normal future?

As the lies propping up Eve's life start to crumble, she no longer knows what she wants. But Gen does, and she's ready to take it.
