Samantha Wolf and Ellie Parker have incredibly good luck! The friends will get to live in a beach cottage for an entire week. They can swim as much as they want, admire the sunsets right by the ocean, and learn to surf. And it’s all because Sam’s dad has been offered a job in the Wooden Bay—a small island town. Sam and Ellie enjoy their summer vacation and accidentally meet the residents of the neighboring cottage: a strange married couple, Lisa and Kevin, and their little daughter Erica. They’re not very happy about the girls’ company—and why does the little girl keep looking for a girl named Carrie? Who is she? Why do Lisa and Kevin pretend everything is fine? Sam and Ellie decide to investigate and begin to suspect that everything happening is somehow connected to an abandoned lighthouse on the Dead Man’s Rock.
