For fans of Stuart Little and Poppy, here is a middle-grade adventure in which a mouse and a shrew, lost at sea, try to navigate to their home in the Great Pacific Garbage Patch. Braving multiple dangers, they discover they have more in common than they could ever have imagined. Mr. Popli, the mouse mayor of Garbage Island, is always at odds with Archibald Shrew, a brilliant but reckless inventor. When Garbage Island splits apart, they're trapped together in Mr. Popli's houseboat, desperate to find their way home. At first, they only argue, but when they face a perilous thunderstorm and a series of predators, they begin to work together and recognize--in themselves and in each other--strengths they didn't know they had. Nonstop action and deep emotion intertwine in this tale of opposites who discover that with bravery, creativity, and friendship, they can triumph.
