New York Times bestselling author Roland Smith delivers the next installment of his bestselling series, this time taking the Wildes on a Galapagos Islands adventure.

Ring and Asia Wilde are back with another outdoor adventure! These siblings' life is anything but ordinary. Some of their closest friends are endangered monkeys and rare birds. Instead of attending middle school, the siblings accompany their parents (scientists who work to save endangered species) on trips around the world.

Now the Ring and Asia are thrilled to be heading to the Galapagos Islands aboard a cruise that will be much more luxurious—and safer!—that they're accustomed to. But on a day of island sightseeing, a volcano erupts and they need to flee. Ring and Asia are stranded on a broken-down Zodiac with a friend and their tutor's twin brother. What's worse is that the ship is long gone. They are well and truly adrift with little hope of rescue. Once again, Ring and Asia will need to use all their skills if they are going to get rescued.
