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 use his special skills 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 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.
