According to Bloodline

According to BloodlineBy Barry SargentA cursed dynasty. A secret society. A woman who was never meant to survive either. Luca Moreau is wealth incarnate-heir to an empire built on silence, blood, and unbreakable control. Devastatingly charming, obsessively private, and haunted by a legacy he can't outrun, Luca leads an elite secret society that manipulates power from the shadows. Their rituals are ancient.
Their influence is absolute. And their rules are written in blood. Dr. Arden Vale doesn't believe in curses. As a forensic psychologist, she believes in motive, pathology, and hard evidence. But when a ritualistic murder pulls her into Luca's orbit, logic begins to fracture. Every clue leads back to the Moreau estate-and to Luca, whose interest in Arden is far more than professional. Lured into a world where madness is a rite of passage and loyalty demands a body count, Arden must decide who she is when everything she thought she knew about identity, control, and legacy is torn away.
Because in the Moreau world, you don't run from the bloodline. You either embrace it. Or you're buried by it. A seductive psychological thriller about power, ritual, and the war between freedom and fate-perfect for fans of Sidney Sheldon, Lisa Gardner, and The Secret History.
