Cleopatra syndrome

Cleo Duval came to New York with a dream of Broadway, but now she's a waitress haunted by blackouts and waking up with no memory of her nights, surrounded by strange clues—a wig, a stain, someone else's money. Her reality fractures further as a relentless detective connects her to a series of brutal murders, and a charming stranger, Paul Randall.
As Cleo delves into the abyss of her own mind with the help of a mysterious psychoanalyst, she uncovers a terrifying truth: she is not alone in her own body. She is the "original," the blueprint for a project known as "Chimera," created by a shadowy organization called The Owl's Claw. Her "sisters"—the volatile Tess and the emotionless, lethal Laura—are not just alters; they are separate, programmed entities, and they are taking over.
Cleo must confront the two other faces in her mirror. She must piece together the fragments of her stolen past and become the one thing she fears most: the perfect weapon they designed her to be.
