Moon Water Madness is the seventh in the Luanne Fogarty series of spine-tingling swamp noir mysteries set in the springs and underwater caves of northern Florida. Luanne, a linguistics professor, serves as adjunct scuba diver for the sheriff's department. Luanne finds herself in over her head when a tough, lonely little girl asks for help. According to legend, Oscar Moon walked into a sinkhole in 1959 and hasn't been seen since. Luanne uncovers more than she expects on an isolated island teeming with snakes, secrets, Spanish moss, and murder.
