Is playing blackjack in the school cafeteria that bad? Samara Brooks doesn't think so. She isn't out to hurt anybody. She just wants to create some drama. And she does. Drama . . . and trouble.

When the principal threatens to call her parents, Samara proposes a way to save herself. She'll prove she's not a bad person by conducting a scientific experiment to show that she has the same DNA as one of the friendliest girls at school: class president Lily Frederick. But then Nathan Weiss, a kid obsessed with UFOs and mysterious codes, gets involved. And things get really weird.

Samara's DNA looks exactly like the eye symbols in the Phaistos Disk and the Voynich Manuscript, a six-hundred-year-old riddle that nobody can decipher - not even professional cryptologists. Does that mean Samara's an alien? Is it a coincidence? Or does it prove something that has never been proven before?
