Ghost of a Chance - Eric Wilder

When P.I. Buck McDivit inherits an island, marina and rustic fishing lodge on a primordial East Texas lake, he finds it's haunted by the ghost of a long-dead little girl. He soon learns the restless spirit is the least of his problems. To keep the property, he must deal with foreclosure, murder, and a group of racists known as the New Southern Right that want the island for their own nefarious purposes. If he doesn't succeed, he won't live to enjoy his inheritance.
