Bob sets out on a dangerous journey in search of his long-lost sister with the help of his two best friends, Ivan and Ruby. As a hurricane approaches and time is running out, Bob finds courage he never knew he had and learns the true meaning of friendship and family.

When her best friend, the sailor Henry Koskela, is falsely accused of murder, a gorilla named Sally Jones visits the run-down docks of Lisbon, embarks on a dizzying journey across the seven seas, and calls on the Maharaja of Bhapur's magnificent court--all in an attempt to clear Henry's name.
