The charming duo returns with a love letter to the library, good friends, the joy of learning, and self-reinvention.

It's Saturday, and Houndsley, Catina, and their friend Bert are looking forward to their weekly visit to the library. But when the trio arrives, they find that Trixie, the librarian, seems different. She doesn't tell a joke or recommend a book like she always does. That's when the friends find out the news -- the library is closing! With Trixie retiring and enrolled in circus school, there's no one to take her place as head librarian . . . or is there? James Howe and Marie-Louise Gay have created another engaging tale about what it means to be a supportive friend and how it's never too late to learn something new.
