With the success of her coffee shop, Cup of Jo, Joanna Coffee is living the life she's always dreamed about. If only people would stop dragging her into murder investigations.

Someone leaves Jo's glaces and an apology letter on the graves of two local teen girls, and Jo feels it's a sign she's meant to solve their murders. The problem is the police don't believe it was murder. They think the girls were unfortunate drowning victims.

Once again, Jo will need to don her detective's hat and prove her ex, Detective Quentin Perry, wrong by putting the guilty party behind bars.
