Marsh Madness by Jana DeLeon

Dying to fit in.

High school wasn’t a grand time for everyone, but when a group of friends decide to meet up at a B and B ahead of their ten-year reunion, old grudges resurface, and one of them ends up dead. Now the owners, a kindly older couple, are on the hook for the accidental death due to anaphylaxis, but they insist no mistakes were made on their part.
Fortune is asked to look into the situation before the inept local sheriff railroads the couple or simply allows gossip to run them out of business, which will cost them their home. Swamp Team 3 heads to Voodoo Island to find a way to clear the couple and finds a complicated mess of locked doors and old secrets awaiting them. Is Voodoo Island really cursed? Or can Fortune unravel the mystery and lead her team to victory?
