Geronimo's reputation is in ruins! Never fear, his cousin Trap has a scheme to save him. All they have to do is fly a rickety old hot air balloon across the ocean, find a mysterious floating silver island, and come home again. Simple, right? But when pirate cats come into the picture, Geronimo and his family must use all their wits to come up with a rescue plan. Will they escape before they become the main event at a roast mouse party? For children aged 5-7 and also available as part of a 10 book box set.
