I invited her into my world—never knowing I was already in hers. To some, my creation is a weapon. To others, it's a safeguard. The system sees all, finds every connection, leaves no secret buried. Yet she found my blind spot. I gave her everything—my bed, my secrets, my trust—the heart I'd buried under years of ambition and isolation. Only to discover she didn't find me by accident. Former CIA. Investigating a deadly leak. Hired by shadows to hunt rumors that could destroy everything I've built. Every kiss was a lie. Every vulnerable moment, a calculated move. She played me like a fucking mark, and I let her. But the fire between us? That was real. And now that same fire might burn us both. I've always been willing to pay any price to protect my creation. Now I'll pay any price to keep her. Even if it means becoming the monster they already think I am. Only the Wicked is Book 1 in the Sinful State series, where elite operatives and ruthless billionaires discover that the deadliest game is the one played with the heart. Standalone romance. No cliffhanger. If you love these characters, the world continues—but this Wicked story is complete. For fans of Anna Hackett, Cynthia Eden, and Julie Garwood.
