Viv Marshall thought the hardest part of her forties would be menopause. She was wrong. The worst battle of her life is only beginning.

Fresh off a painful breakup and fighting the sudden onset of perimenopause, Viv is convinced her body and mind are turning against her. Blinding hot flashes. Sudden, terrifying bursts of rage. Crimson drops of blood appearing everywhere she looks. When doctors offer answers that don’t add up, Viv assumes she is simply unraveling.

Hidden within her family’s estate lies an unexpected inheritance: the Devil’s Heart Diamond. A cursed, heart-shaped relic that brought her grandfather luck and her father tragedy, it now sits silently in her summer beach house like a ticking bomb.

It takes a chance encounter with a psychic medium at a carnival for the true nightmare to take shape. Viv isn't going mad. Something ancient and evil has attached itself to her, feeding on her rage and drawing power from her deepest despair.

As the physical world begins to bleed into a horrific reality, Viv must decide who to trust: the ex-boyfriend begging to come home, the psychic medium who makes a living telling lies, the coworker who may not have her best interests at heart, or her own fracturing senses.

Grounded, visceral, and dripping with claustrophobic dread, The Red Possession is an edge-of-your-seat psychological horror exploring trauma and the horrors of the female body. It is perfect for fans of The Substance, Motherthing, and The Exorcist.
