Lori Rater-Day, Under A Dark Sky
If you like your mysteries with a lot of backstory, an anxious protagonist, and a complex plot, this could be the novel for you. Eden Wallace’s life has been one of anguish and sorrow since the death of her husband in an automobile accident. So when she finds that her husband has reserved a week at a dark sky park, where you go to observe the stars, she decides to go.
There she is forced to share her cottage with a group of folks in their late twenties, all fixated on their college friendships of years before. When one of the friends is murdered, everyone becomes a suspect, including Eden. As the story unfolds we find that nothing is as it appears to be with the friends, with Eden, or with the deceased husband.
Those who like rather literary mysteries with lots of angst will find this enjoyable.
