Sammy Keyes and the Showdown in Sin City

Sammy Keyes is relentless when it comes to solving mysteries. Well, the mysteries in other people's lives. The big, uncomfortable questions in her own life are much harder to crack. Like:
-Who is her father? And why has her mother kept it such a secret?
-How long can she manage to hide out in Grams' seniors-only building before someone catches on and kicks them both out?
-Is her mother really planning to marry her boyfriend's father? (Ew.)
-And why, why is Heather Acosta so nasty?

But now, during one crazy weekend in Las Vegas, she is determined to get some answers. Even if it means she has to beg, borrow, and steal (and stow away, lie, and bribe) to do it.

Of course, knowledge comes at a price-and solving the mysteries of her own life may cost Sammy more than she ever meant to pay.
