Two families go on a cruise, bringing their kids along. Everything is going swimmingly until they go on an excursion and everything goes to hell. The adults end up separated from the kids, and the kids end up getting kidnapped. The story alternates between the perspective of both the adults and the children. It was anxiety inducing and scary but it just kind of left me wondering why I’d spent hours reading. I didn’t get much out of it, there weren’t any twists, and it dragged for long stretches. This book is just okay.
