One murder shall set her free, or make her more a prisoner than she has ever been.

All Andromeda wants-all she has ever wanted-is freedom. It should be easy enough to get for a teen girl who can unlock doors with her mind. Nevertheless, she's lived the entirety of her life under the thumb of the abusive Zia-the closest thing she has to a mother-and in reach of the inescapable arm of her controlling brother Orion. But everything changes the day Zia makes her an offer: Andromeda can be free, and she never has to see Zia again. All she has to do is kill one person-Perseus.

But who is Perseus, the boy selling ice cream in Washington Square Park? Why does Zia-and not only Zia-want him dead? And what happens when Zia disappears, the world turns upside-down, and Andromeda finds herself escaping New York City with Perseus by her side?

In the globe-spanning adventure that follows, Andromeda will learn the truth about herself, and Perseus, and Orion, and all those like them-Star Children, with abilities beyond reason and scars that shine in the night. But the truth may well not set her free.

It may make her more a prisoner than she ever was before.
