The Dream Stealer — Sid Fleischman

What would you do to rescue your most precious dream?

Susana's best friend moved away, and now the only time Susana can see her is in her dreams. Until one night when the dream suddenly ends. The Dream Stealer has come, her grandmother says. The Dream Stealer does not want pretty silver earrings or dangly gold necklaces, diamonds or rubies. He wants dreams. He's supposed to take only nightmares, but he's grown scared of the monsters and phantoms. He's been stealing good dreams instead. But he's stolen from the wrong girl.

Susana is clever. She is fearless. And she wants her dream back.
