To a small field mouse from Massachusetts, family is everything! A lovely leather journal chronicles all the important events of his family's history. When the journal is destroyed in a flood, Nicholas will set off across the state of Massachusetts in search of his uncle and a copy of the precious book. Along the way, he'll meet many friends and explore the many diverse areas that make up Massachusetts-the Berkshire Mountains, Quabbin reservation, Wachusetts, Gloucester, Boston, Plymouth, and finally Martha's Vineyard.

Book One in a four-book series about Nicholas's adventures in the Northeast.
