After young Kirra leaves her Australian home to summer with her grandfather in South Africa, she soon discovers a baby orca stranded in the lagoon near her grandfather’s rundown seaside amusement park. She names the lonely whale Willy--and embarks on a great quest to lead the little guy back to his anxious pod.

Fourteen year old Nim, more determined than ever to protect her island and all the wildlife that call it home, faces off against resort developers and animal poachers. Soon she realizes she can’t depend on her animal cohorts alone and must make her first human friend – Edmund, who’s run away to the island from the mainland – to save her home.
