In a Dark, Dark Wood by Ruth Ware

Nora is presented with a puzzling dilemma as the story begins: whether or not to attend a hen weekend (bachelorette party) for her estranged best friend. After being goaded to attend by and with a mutual friend, Nora learns how much can change in ten years, but also how much can stay the same. The party of six find themselves in the middle of a murder investigation at the end of a weekend of intoxication and isolation in the woods. A knock on the head prevents Nora from remembering what happened until it might be too late.

Though there are a couple good moments of hold-your-breath suspense, I found some of the more important details of the story to be illogical. I enjoyed reading about the British version of a bachelorette celebration.
