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 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, 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.
