But there's a sliver of water called "Sin Creek" by some, where wickedness and decadence take precedence over decency. Logan Hunter battles evil on her quest to find a co-ed's killer and keep her marriage to another agent from falling apart. Even though she succeeds in finding the killer, the investigation changes her life in ways she never could have imagined.
