Under a dark sky

What an intriguing concept - fashioning a locked door mystery at a dark sky retreat. I'm a sucker for “college chums gather together again but they're keeping a secret” and also for a woman restarting her life after a painful tragedy so this rang all my bells. Good pacing, rich characters, and such a touching, sad backstory to Eden's marriage that it truly touched my heart. I know Rader-Day doesn't usually do sequels but I'd love to catch Eden in a future book of hers.
