Sea Otter Sunrise

The #1 bestselling Magic Tree House series whisks young readers away on another thrilling adventure—this time to the sun-drenched shores of Monterey Bay, California, where Jack and Annie must help save an injured sea otter after a shark attack.

When the magic tree house lands bright and early on the California coast, Jack and Annie face an unexpected mission: collecting sea urchins in the underwater kelp forests. There’s just one problem—they know absolutely nothing about sea urchins! With the help of a grouchy boat captain (who might just have a heart of gold beneath that crusty exterior), they begin to learn the ropes. But when Annie discovers a badly injured sea otter struggling to survive, the siblings face an impossible choice. They’re not supposed to help the otter… but how can they turn away?

Perfect for young readers transitioning from picture books to chapter books, this action-packed tale blends adventure, marine biology, and important lessons about compassion and doing what’s right—even when it’s difficult. Mary Pope Osborne’s beloved characters continue to inspire curiosity about the natural world while delivering page-turning excitement that keeps kids reading.

Whether your young reader is just discovering the Magic Tree House series or collecting every adventure, Sea Otter Sunrise delivers the perfect combination of education and entertainment that has made this series a perennial favorite in classrooms and homes across the country.
