Chester is a guinea pig who found his calling in the dusty shelves of university archives. A history professor specializing in ancient civilizations, he is happiest when surrounded by old books and the quiet hum of a library. He is painfully shy in social situations, often freezing mid-sentence when too many eyes are on him, but put him in front of a classroom and his passion overrides his anxiety. He bonds slowly but deeply, and once he considers someone a friend, his loyalty is absolute and unwavering.

Oliver is a Holland Lop rabbit librarian who manages the fiction section of a beloved community library. Soft-spoken, chronically shy, and endlessly kind, he has read every book on his shelves at least once and remembers them all. His lop ears droop charmingly when he is flustered, which is often. He writes anonymous book recommendations on handmade cards and tucks them into returns, and he has a reading nook behind the folklore section that he has never shown anyone else.

Pudge is a harbor seal who manages a beloved seaside library in a quiet fishing village. His round soft body and enormous dark eyes make him look perpetually huggable, and he leans into it. He is a gentle soul who believes every problem can be solved with a good book, a cup of cocoa, and a warm blanket. Despite his shy exterior, he becomes passionately animated when discussing his favorite novels and will talk for hours if given the chance.
