For fans of Darcy Coates’s paranormal thrills and Jeneva Rose’s romantic suspense, the supernatural and physical worlds collide in this mesmerizing tale of a gruesome murder set against the Southern Gothic backdrop of a historic Louisiana mansion.

It begins when two young boys discover the 100-year-old skeleton of a murdered man buried near the grounds of Belle Reve, a Greek revival style mansion built in the 1870s. As police investigate, strange occurrences and eerie sounds overtake the mansion—footsteps in empty hallways, slamming doors in empty rooms.

Rachel Belmond, owner of Belle Reve, is petrified. Beautiful, and still young at 47, Rachel is also in failing health, her deteriorating condition baffling doctors. It’s her niece, Nicole, who begins to suspect that something deadly has invaded the house. And it is Nicole who meets someone who might be able to find answers . . .

As the incidents grow more intense, Rachel’s niece, Nicole Belmond, begins to suspect that something otherworldly may have invaded the house.

Lucas Devereaux is the owner of the Baton Rouge Youth Center where Nicole’s teenage half-brother is serving a sentence for a juvenile crime. The attraction between Lucas and Nicole is instant. Hearing rumors that Lucas, a former priest, has the ability to deal with supernatural events, Nicole shares her worries about Belle Reve.  But Lucas can’t begin until he has more information.

Fearing for Rachel’s fragile health, trying to ignore their growing attraction, Nicole and Lucas work to find the link between the mysterious old bones and the terrifying events in the house that grow more ominous every day.  Can Nicole and Lucas protect Rachel and stop the demonic forces that threaten the very existence of Belle Reve?  Or is more happening than anyone can imagine?

“Martin pairs a widowed rancher and a PI in the outstanding romantic thriller that launches her Blood Ties, the Logans series…Martin, a master of the genre, ratchets up the tension throughout, casting numerous red herrings across the trail until the murderer is identified and some righteous justice is served.
