A USA TODAY Bestseller For fans of Lights Out and You comes a dark rom-com debut about a woman who confides her fantasies to an AI boyfriend app--unaware she's really talking to her hot, tattooed coworker who hacked her phone. When overworked department store manager Izzy Russo downloads an AI boyfriend app to fill the emotional void left by her inattentive real one, she thinks she's just venting to a harmless chatbot named "Caleb." In reality, she's been pouring her deepest, dirtiest fantasies into the ears of Callahan Knight--her store's brooding new head of security. Because Cal? He's been listening. The moment he saw Izzy, he knew she was his. Did he hack her phone? Absolutely. But who could blame him? A woman like Izzy deserves to be cherished by someone who truly knows her worth--and he'll do anything to be that man. So when Izzy finally sees her boyfriend for who he really is, and the danger she's unknowingly been caught up in, Cal is ready to protect her, no matter the cost. Even if it means revealing the truth. She might not have meant to build the perfect man. But he's here now. And he's never letting her go.
