Three years ago, Elena Carter was declared dead after a mysterious car accident. Her family held a funeral, the newspapers reported her death, and the case was eventually closed. However, Elena survived the accident and disappeared from New York with the help of her closest friend, Lucas Bennett, who was the only person who knew she was still alive. She changed her identity to Emily Hayes and built a quiet life away from her dangerous past. Three years later, she returns to New York and becomes the executive assistant to billionaire CEO Adrian Blackwood. Adrian is cold, ruthless, and impossible to deceive. When he discovers that Emily is actually Elena, the woman everyone believes is dead, Elena expects him to expose her. Instead, he makes her an unexpected offer. "Become my fake fiancée, and I'll protect you." Elena accepts because someone has discovered that she survived. However, Adrian has another reason for the arrangement. Someone inside his family is secretly sabotaging his company, and he believes Elena's past may be connected to the traitor. Forced to live together and pretend to be in love, Elena and Adrian slowly develop real feelings for each other. But Lucas remains close to Elena, just as he has been since before her disappearance, and Adrian finds himself becoming jealous of their relationship. As Elena and Adrian investigate the mystery, people connected to her past begin dying, and someone sends her a terrifying message: I KNOW YOU SURVIVED. Then Elena discovers Adrian's biggest secret. He knew who she was long before he offered her the fake engagement. Now she doesn't know whether Adrian truly loves her or whether she was only a part of his plan.
