When Talia Halden rescues a wounded billionaire hiding from killers, she has no idea she's opening the door to the one man who can destroy her life. He calls himself Kairo Sinclair—powerful, mysterious, and haunted by secrets he refuses to share. Trapped together in a remote mountain cabin, fear gives way to trust... and trust becomes a love neither of them can stop. Until another billionaire appears. With the same face. The same name. And one devastating truth. The man Talia loves has been lying from the moment they met. Now every kiss feels like a betrayal. Every answer uncovers a darker secret. And every step toward the truth pulls them closer to the people who murdered her mother. But the most dangerous secret isn't who he really is... It's why he spent years protecting her before she ever knew his name. In a world where love and deception are impossible to separate, Talia must decide whether to run from the man who broke her trust... ...or risk everything for the only man willing to die to keep her alive.

Lucia Santoro is a ghost. Known only as "La Vipera" in the blood-soaked underworld of contract killing, she's never missed a target, never hesitated, never felt. But when a job in Rome goes catastrophically wrong, she's forced to do the unthinkable—disappear into the heart of her enemy's fortress. She infiltrates the Marchetti crime family as a traumatized witness under their protection, playing the perfect damsel: fragile, grateful, broken. It's the role of her life. And the most dangerous lie she's ever told.Dante Marchetti didn't become his family's most feared underboss by trusting scared girls with secrets in their eyes. Every instinct screams that Lucia is wrong—too controlled, too careful, too aware. So he keeps her close, watching her every breath, testing her every word, waiting for her to slip. But proximity is a weapon that cuts both ways. The more he hunts for her truth, the more he's haunted by the fire he sees beneath her fear. She's not a victim. She's a storm pretending to be still water.What neither of them knows is that they're circling the same prey. Dante has spent years secretly plotting to annihilate his own family from within after discovering their involvement in child trafficking—the one sin even his blood-stained hands won't touch. Lucia's contract? Destroy the Marchetti empire for those exact crimes. They're both assassins wearing different masks, both alone in their wars, both convinced that salvation died long before they learned to kill.When their missions collide in a brutal confrontation that leaves bodies scattered and truths bleeding out, they're faced with an impossible choice: complete their assignments and destroy the only person who's ever truly seen them, or shatter every vow they've made to themselves. Dante has never wanted to save anyone—until he met her. Lucia has never wanted to be saved—until she met him.In a world built on betrayal, love isn't soft. It's vicious and consuming, a venom that poisons everything it touches. But maybe, in the ashes of the empire they burn together, two broken people can discover that the most dangerous thing they've ever done is learn to trust someone else with the knife.Sometimes the only way out of the darkness is to find someone willing to burn in it with you.
