Where some people see rubbish, Rosie Revere sees inspiration. Alone in her room at night, shy Rosie constructs great inventions from odds and ends. Hot dog dispensers, helium pants, python-repelling cheese hats: Rosie's gizmos would astound - if she ever let anyone see them. Afraid of failure, she hides them away under her bed. Until a fateful visit from her great-great-aunt Rose who shows her that a first flop isn't something to fear - it's something to celebrate.
