Island Mystery
Saint X is full of mysteries. Alison is a mystery to her younger sister Clairy. Alison's disappearance is a mystery. Alison's killers are a mystery. Their motives are a mystery. While the first impression is fairly long, it only covers what appears to be an introduction to how the rest of the story plays out about an older Claire. Intriguing, but not so compulsively so that I can't put it down.
