Kya Clark is the "Marsh Girl" of Barkley Cove on the North Carolina coast. Abandoned at age ten, she has survived on her own in the marsh that she calls home. A born naturalist, she took life lessons from the land, learning from the false signals of fireflies the real way of this world. Drawn to two young men from town who were intrigued by her wild beauty, Kya opened herself to a new and startling world-- until the unthinkable happens. When Chase Andrews is found dead, the locals immediately suspect Kya.
