Twin Sins: Book 3, The Sins Volumes

Accused of rape, a U.S. Senator struggles to recall the implausible events that occurred during a fundraiser held on his behalf at the luxurious DeLuca mansion in Southampton. Found lying unconscious by the swimming pool, Senator Sid Taylor can't remember anything after an argument he had with his accuser, Sophia Giordano, the young and beautiful President and CEO of DeLuca Enterprises.
The Senator's wife, Valentina, is more concerned about her good standing within the powerful family than she is about the well-being of her distant cousin, Sophia. However, friends and relatives closest to Sophia plot to seek revenge on the apparent perpetrator of the heinous act-no matter who it may hurt in the process. However, those actions lead to a series of unintended consequences, including drug overdoses, mass murders, kidnappings, embezzlement, and suicides.
The family's attorney and close friend, Caroline Norton, takes the personal initiative to hire a Private Investigator to gather information on the Senator's potentially shady background. The investigator, Raymond "Slick" Silvio, aided by psychic visions and paranormal interactions with friendly spirits, discovers more than he bargains for as the sins he unearths begin to accumulate.
As Slick and Caroline get closer to the truth, surprising twists and turns lead them in directions they never expected to go. Will Caroline be forced to reveal the secrets she swore to keep more than 20 years before? Will she divulge the truth, even if it devastates the families who she promised to protect and love?
