Adventure awaits and Mup is ready for it. But with one bad wish, a creeping disaster unfolds and Mup finds herself in the future, face-to-face with the one person she never wanted to become: her teenage self! Can the two girls work together to uncover the secret to the planet's survival before it's too late?

This first book introduces the core MUP idea: a wild, funny adventure that still lands emotionally. The story keeps the stakes personal and the pacing quick, so reluctant readers can jump in without feeling weighed down.

"A rollicking adventure that explores the themes of environmental stewardship and rejuvenation — all layered on top of a poignant tale of the inner struggle for identity caused by growing up. A must read for graphic novel lovers of all ages."— Jennifer Overaa, Librarian, San Anselmo Public Library
