"I was the wife he forgot. Now, I’m the nightmare he can't escape." Caesar Harlow is the "Cold Emperor"—ruthless, brilliant, and amnesiac. He thinks his life is perfect, until a new assistant walks into his office with eyes that haunt his dreams and a mind that rivals his own. Leo Thorne is the "Shadow King"—the childhood friend who pulled Stella from the wreckage and gave her a new face, a new name, and a reason to live. He’s waited twenty years to claim her, and he won’t let a Harlow steal her twice. Stella is the variable. She’s caught between the husband who forgot her and the man who would die for her. As she infiltrates the Harlow Empire, the lines between hate and desire begin to blur. How do you destroy a man who doesn't remember breaking your heart? You make him fall in love with you all over again—and then you walk away.
