Best-selling author Daniel Kirk's Library Mouse was praised by Booklist as a "showstopper." In A Museum Adventure, Sam the library mouse and his friend Sarah visit a museum so that Sam can sketch in his explorer's journal. Sarah doesn't understand how explorers can possibly have the time-or the desire-to keep a journal. So Sam shows her how a journal can contain so much more than just writing. As the friends search the museum, they see many new things-and make an unexpected friend.
