Otis and Sydney are the best of friends. This year, Otis wants to do something special for Sydney’s birthday. So he decides to throw a surprise party and invite all their friends. He mails the invitations, decorates the house, and bakes a cake, but when things don’t go as planned, how will Otis make sure that Sydney has the best birthday ever? A sweet and tender tale by the New York Times #1 bestselling author of If You Give a Mouse a Cookie and the Jellybeans series, Otis & Sydney and the Best Birthday Ever introduces young readers to two lovable bears who understand that friendship is the only thing needed to make any day special. "Andreasen's digitally colored pen-and-ink drawings nearly jump off the page, maximizing the similarities between the two unabashedly adorable bears and frequently arranging themselves in paneled vignettes whose balance further reinforces the harmony between the two—just right for this simple story of friendship for the very young." — Kirkus Reviews "Books don’t come much cozier or any less threatening than this." – Booklist
