Eva's life is not her own. She is a creation, an abomination - an echo. Made by the Weavers as a copy of someone else, she is expected to replace a girl named Amarra, her 'other', if she ever died. Eva studies what Amarra does, what she eats, what it's like to kiss her boyfriend, Ray. So when Amarra is killed in a car crash, Eva should be ready.
But fifteen years of studying never prepared her for this.
Now she must abandon everything she's ever known - the guardians who raised her, the boy she's forbidden to love - to move to India and convince the world that Amarra is still alive. . .
