A National Book Award finalist by Newbery Medalist Kate DiCamillo. Twelve-year old Rob Horton likes to wander through the misty forests of Florida until one day, he is stunned to encounter a caged tiger. A real life, very large tiger, pacing back and forth. Moreover, that same day he meets Sistine Bailey, a spontaneous girl who wields her personality with the same speed in which Rob hides them. As they learn to trust each other and ultimately be friends, Rob and Sistine will discover how memories, heartaches, and tigers can't be locked up forever.
