The New York Times bestselling authors of Bob, Rebecca Stead and Wendy Mass, introduce readers to a little free library guarded by a cat and a boy who takes on the mystery it keeps.

When a mysterious little free library (guarded by a large orange cat) appears overnight in the small town of Martinville, eleven-year-old Evan plucks two weathered books from its shelves, never suspecting that his life is about to change.

Evan and his best friend Rafe quickly discover a link between one of the old books and a long-ago event that none of the grown-ups want to talk about. The two boys start asking questions whose answers will transform not only their own futures, but the town itself.

Told in turn by a ghost librarian named Al, an aging (but beautiful) cat named Mortimer, and Evan himself, The Lost Library is a timeless story from award-winning authors Rebecca Stead and Wendy Mass. It’s about owning your truth, choosing the life you want, and the power of a good book (and, of course, the librarian who gave it to you).
