She can't remember the attack that almost killed her. He's the one man who knows her secrets.

A brutal murder triggers terrifying, fragmented nightmares for Detective Serenity Bright, but her own past remains a total blank. Now, she's forced to partner with the one person who might have answers: the enigmatic and wealthy Ethan Knight, a man inextricably linked to the past she can't recall.

As a serial killer's terror grips the city, every clue Serenity uncovers points to a shadowy organization and a chilling conspiracy tied to her own forgotten identity. Ethan, with his elite military skills and shrouded motives, is both her protector and her prime suspect. Their sharp, combative partnership sizzles with a dangerous attraction, blurring the lines between ally and enemy as they navigate a deadly game of psychological warfare.

With her mind a battlefield and a killer closing in, Serenity faces an impossible choice: trust the man who may have broken her, or risk letting the secrets of her past get them both killed.
