A very special mouse embarks on an epic adventure to find his missing family in this acclaimed #1 New York Times bestseller from James Patterson, perfect for fans of Stuart Little and The Mouse and the Motorcycle.

What makes Isaiah so unique? First, his fur is as blue as the sky—which until recently was something he'd never seen, but had read all about. That's right: Isaiah can read and write. He can also talk to humans . . . if any of them are willing to listen!

After a dramatic escape from a mysterious laboratory, Isaiah is separated from his "mischief" (which is the word for a mouse family) and has to survive in the dangerous outdoors, and hopefully find his missing family. But in a world of cruel cats, hungry owls, and terrified people, it's hard for a young, lone mouse to make it alone. When he meets an equally unusual and lonely human girl named Hailey, the two soon learn that true friendship can transcend all barriers.

★ "Isaiah is truly a mouse that roars."―Kirkus Reviews (starred review)

★ "Children's literature offers a long tradition of clever mice who accomplish amazing feats, and Patterson and Grabenstein's Isaiah seems destined to join them. Here's hoping this unique hero returns soon with further adventures."―Booklist (starred review)
