DOUBLE IDENTITY

As Bethany approaches her 13th birthday, her parents act more oddly than usual: Her mother cries constantly and her father barely lets Bethany out of his sight. Then one morning he hustles the entire family into the car,drives across several state lines-and leaves Bethany with an aunt she never knew that existed.Bethany has no idea what's going on. She's worried her mom and dad are running from some kind of trouble,but she can't find out because they won't tell her where they are going.
Bethany's only clue is just a few words that she overheard her father tell her aunt: "She doesn't know anything about Elizabeth." But Aunt Maurie won't tell Bethany who Elizabeth is, and she won't explain why people in her small town react to Bethany as if they've seen a ghost.
The mystery intensifies when Bethany gets a package from her father containing four different birth certificates from four different states,with four different last names-and thousands of dollars in cash. And when a strange man shows up asking questions,Bethany realizes she's not the only one who's desperate to unravel the secrets of her past.
