The scope is so ambitious, though, that the story can feel convoluted in some places, while it's oddly thin in others. The island, including the family house and the quarry where some pivotal action takes place, is described in minute detail many times over, while certain subplots remain unexplored. Some aspects of the Fowler and Volt family mythology are revisited to the point of redundancy, while others go unaddressed. Moulton builds a fascinating world but never quite establishes its rules. Still, each point-of-view character who narrates the story... pulls off her piece to tell an engrossing tale.
