To earn money for dog food, Jem gets a job from Mr Sims, the café owner. All he has to do is catch bullfrogs for the menu-what a perfect task for an active boy! But Jem's dog, Nugget, and his little sister, Ellie, get in the way, and Jem gets angry. Now Ellie is gone—and no one knows where! Jem knows it's his fault she's missing. Can he find her before it's too late?
