scatterbrained books

When Mary moved out of her parents' house, she didn't figure being cut off from the family. But that's just what her mom has done--she's not welcome to family dinners, holidays, or any other functions. So Mary is completely caught unaware when her stepdad tells her that her teenage sister, Sally, has gone missing.

Unwilling to sit back and wait for her parents' next move, Mary springs into action. Did Sally run away? Was she taken? Was it her secret older boyfriend? A jealous classmate? One thing is for sure: no one can pull off that disappearing act, not without help. Or death.
