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...

When her abuelo is injured at the local landfill, second-grader Sofia is determined to transform the dangerous Mount Trashmore into a park, taking on City Hall in the process.

When Lila, a worrier, moves to a new town, the what ifs only grow, and she feels alone and invisible until her teacher finds a creative and kind way to make Lila feel welcome and open to new experiences, a lesson that will stay with her long after second grade.
