Word of Mouse [EPUB ebook] 

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 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.
