Former MI6 assassin Kaelen Vance is hiding in plain sight as a history professor in Oxford, his violent past buried under a mountain of books and regret. His fragile peace shatters when Dr. Aris Thorne, a brilliant, fiercely independent art historian, deciphers a code that threatens to expose a shadowy syndicate he once worked for. Thrust together as targets, their only hope for survival is a stolen data key hidden in a Venetian palazzo. But as they navigate a treacherous game of cat-and-mouse across Europe, a dangerous spark ignites between them. Kaelen is torn between the oath he swore to protect her and the terrifying realization that to save her, he might have to become the monster he promised her he'd left behind.
