(4) Middle schooler Samantha runs a secret-passing business: kids put anonymous notes in her locker and she delivers them, unread. The system works well until Samantha finds herself the go-between for her crush and another girl. The realistic ways the protagonist works out her problems with boys, friends, and family fleshes out the rather meager plot.
