Houndsley and Catina at the library

"It's Saturday, and friends Houndsley, Catina, and Bert always go to the library. But when the trio arrives, librarian Trixie is sad. She doesn't tell a joke or recommend a book. That's when the friends find out the bad news: the library is closing because With Trixie retiring and off to circus school, there's no one to take her place as head librarian. Or is there?"--Provided by publisher.
