Best-selling author Daniel Kirk's children's books include Library Mouse-which Booklist called a "showstopper." In the library, Sam meets a fellow mouse named Sarah, who is quite an explorer. Scurrying along the tops of the bookshelves and scampering around in the darkest corners are some of her favorite pastimes. How different from Sam, who is too frightened to climb! Sam would much rather spend his time learning about new things. In the end, the two can do just about anything if they work together.
