He is feared by many, trusted by few, and watched by someone who refuses to stay hidden. As a powerful member of the Russian Bratva, Kyle Petrov has spent years building a reputation that makes grown men tremble. Enemies don't scare him. Betrayal doesn't surprise him. But the red envelopes that keep appearing wherever he goes are something else entirely. Each envelope contains a note marked with a crimson kiss. A warning. A promise. A reminder that someone is always watching. Determined to uncover the identity of his stalker before her obsession turns deadly, Kyle is forced to seek help from the last person he ever wanted to see again-Katya Sokolov. His childhood friend. His sworn enemy. The daughter of the man responsible for his parents' deaths. Now one of the most talented hackers working within the Bratva, Katya has spent years trying to forget the boy who grew into the man who hates her. But when Kyle comes to her for help, she finds herself pulled into a dangerous investigation filled with secrets, lies, and a stalker who seems to know everything about him. As the mystery deepens, so does the tension between them. Old wounds refuse to heal, yet neither can ignore the attraction that burns beneath their hatred. With every clue they uncover, the line between enemy and ally becomes harder to see. But someone is watching their every move. Someone who will do anything to have Kyle Petrov. And the closer Kyle and Katya get to the truth, the closer they get to becoming the stalker's next victims. In a world ruled by obsession, revenge, and betrayal, can two enemies learn to trust each other? Or will the secrets of the past destroy them before they ever get the chance? One stalker. One mystery. One irresistible attraction. And a kiss-marked envelope that changes everything.

Because somewhere between the nightmares and the truth- between hatred and something far more dangerous- someone is already unraveling everything she tried to hide. And when the past finally catches up to her... she won't just lose her heart. She might lose herself.
