Minnesota private investigator Jane Lawless plans to visit her old friend Emma in her hometown of Castle Lake, and they are looking forward to an upcoming high school reunion for the class of 1999. But back in their school days, Emma's boyfriend Sam went missing, and now his remains have been found in someone else's burial plot. The killer may be at the reunion, and in this 27th case (after Twisted at the Root) it's up to Jane to sort the innocent from the guilty, before it's too late.
