As Ezzy Skylar's mother lay dying, her father promised to take Ezzy and her younger brother, Luke, to all of the places on his wife's wonder-list, starting with the Galápagos Islands. There's just one problem: while Luke loves all living things, Ezzy freaks out around wild animals. For her family, Ezzy must face her fears and walk with iguanas, swim with sea lions and sharks, and pretend to dance among blue-footed boobies. Things take a dangerous turn when hijackers take over their cruise ship. Ezzy, Luke, and Aiden, a teen they meet on the ship, are stranded on remote and wild Isabela Island, where an erupting volcano adds to the action and adventure. Ezzy must find bravery she never knew she had and rely on her little brother's help to make their way across the island in an attempt to rescue a ship full of tourists and the animals of the Galápagos.
