Unquiet Spirits - Dangerous Waters Trilogy, #3

Dashing heroes set out to protect the women of their dreams as they travel by boat over the Caribbean and the Bahamas, even to a clear lake in Muskoka, where romance--and deception--will take them all into Dangerous Waters. Headstrong Kit Schofield heads north to her family resort at Spirit Lake, convinced the hit-and-run that almost killed her was a random act of violence. Not-so-convinced, lifelong buddy Bart Thornton joins her as a self-appointed bodyguard, much to Kit's chagrin--at first.
Two lusty ghosts drop clues about old murders and insist that Kit and Bart are soul mates. One kiss proves it, unleashing unexpected, unwelcome and totally distracting passion between them. Disturbing old secrets and equally unsettling ghosts lurk in the lodge as well as in the calm waters of the deceptively peaceful resort. In the calm, a deadly, elusive killer strikes again...
