Bloody Point — Linda J. White

After her agent-husband is murdered, young FBI agent Cassie McKenna takes a leave from the Bureau to try to find serenity on her sailboat that's moored on the beautiful Chesapeake Bay. But serenity is the last thing she finds. Breakneck twists follow the chilling realization that a series of strange events are anything but a coincidence, and if Cass' hunch is correct, there's more at stake than she ever dreamed.
