El Príncipe Rana y la zoologa (The Frog Prince and the Zoologist)

Clem loves swimming in Pleasant Pond, especially when her friend Tessa Troll buys a cottage beneath the pond's bridge. The bridge is old, so Tessa tries to warn anyone who comes near it. But her warning scares off two of the Billy Goat brothers when they think she's going to eat them. Looking Glass Library is an imprint of Magic Wagon, a division of ABDO. Professionally translated.
