BETRAYAL OF THE HEART

The person who holds your heart might be the one trying to stop it. Dr. Julianne Vance is a brilliant cardiologist who prides herself on understanding the human heart-its rhythms, its flaws, and its breaking points. She lives a seemingly flawless life in a beautiful home with her charming, fiercely protective husband, a high-profile pharmaceutical executive. They are the city's golden couple, built on a foundation of absolute trust.
Until a highly unusual patient is admitted to Julianne's cardiac ward. The patient arrives with a rare, undetectable toxicity in his bloodstream-a chemical compound that mimics a natural heart attack perfectly. Before slipping into a coma, the man clutches Julianne's arm and whispers a warning that shatters her reality: a warning containing an intimate, private nickname that only her husband uses.
Driven by an unsettling instinct, Julianne begins a quiet, off-the-books investigation into her husband's corporate research files. What she uncovers is a dizzying labyrinth of medical fraud, missing clinical trial data, and a trail of unexplained deaths dating back a decade. The husband she thought she knew is actually a master manipulator, weaponizing medicine to eliminate anyone who threatens his empire.
But playing detective against a brilliant sociopath under your own roof is a dangerous game. As Julianne tries to gather evidence without raising suspicion, her husband shifts his tactics. The manipulation begins subtly-prescriptions switched in the night, medical records altered to make Julianne look erratic, and gaslighting that leaves her questioning her own sanity. Soon, the police department looks at Julianne as the prime suspect in her patient's poisoning, guided by a flawless breadcrumb trail of electronic evidence planted by her husband.
Trapped in a claustrophobic psychological warzone where her house is monitored, her career is ruined, and her closest friends are turned against her, Julianne must use her clinical intellect to survive. She must beat him at his own cold-blooded game. Because in this house, a racing heartbeat isn't a sign of love-it's a countdown to an execution. Betrayal of the Heart is a sharp, fiercely fast-paced psychological suspense thriller packed with medical intrigue, domestic paranoia, and shocking, knife-edge twists.
Perfect for fans of The Silent Patient, Gillian Flynn, and Behind Closed Doors.
