The Daring Escape of the Misfit Menagerie — Jacqueline Resnick

Smalls the sun bear and his friends are an unusual bunch. That's why they're known as the Misfit Menagerie. The four oddball animals live on Mr. Mumford's farm, where they play games and do tricks for neighborhood children. It's an idyllic existence--until a cruel circus owner named Claude Magnificence comes to town, and life as they know it ends. The Menagerie is snatched away to a traveling circus, where Claude and his buffoonish sidekicks force them to perform death-defying tricks.

At the circus, Smalls and his friends only have slop to eat. They live in filthy, cramped cages. And they're bullied by a rough band of trained animals called the Lifers. It's worse than awful--it's despicable! But then young Bertie Magnificence comes along, and he and Smalls form the kind of friendship that inspires hope. They decide that something needs to change...and fast. With the help of an acrobat named Susan, Smalls and Bertie set in motion a heroic plan.

Can a lonely boy and a misfit bear hoodwink cruel Claude and save an entire circus of captive animals?
