When death threats force reclusive tech heiress **Elena Voss** to hire elite bodyguard **Kai Mercer**, she expects cold professionalism—not the man whose life she destroyed five years ago. Kai took the job for one reason: revenge. He blames Elena for the court-martial that shattered his best friend’s life and his own trust in justice. Trapped together in her family’s storm-locked estate after an ambush, their hatred ignites into something far more dangerous: reluctant attraction. But as hidden passages, coded messages, and a ghost from Elena’s past resurface, they uncover a chilling truth—her father’s empire was built on a secret military project called **Nightingale**, and someone wants them both silenced. Worse, the stalker’s voice sounds eerily like Elena’s mother… who died a decade ago. As mercenaries close in and old wounds reopen, Kai must choose: protect the woman he swore to hate, or let the past bury them both. In a world of lies, the only truth left is the one beating between them—ruthless, raw, and impossible to ignore. *Guarded Hearts* is a high-stakes enemies-to-lovers romantic suspense with forced proximity, buried secrets, and a love forged in fire. Perfect for fans of *The Bodyguard* and *Verity*.

He bought me at an auction. ‎He knew my name before I spoke it. ‎And he’s the reason my parents are dead. ‎ ‎Elena Voss infiltrated Monaco’s most exclusive underground auction with one goal: get close to Dante Moretti—the ruthless heir who stole her family’s legacy and watched their home burn. Posing as an escort, she never expected him to recognize her… or to whisper her brother’s name like a threat. ‎ ‎Now, trapped in his gilded penthouse, she’s forced to restore the very painting that holds the key to her parents’ murder—the Mourning Madonna. But the closer she gets to the truth, the more dangerous Dante becomes: cold, commanding, and haunted by secrets that tie him to her past in ways she never imagined. ‎‎He says he loved her mother. ‎He says he let her live for a reason. ‎And he says if she betrays him, her brother dies next. ‎‎In a game of lies, lust, and vengeance, can she destroy the devil… or will she fall for him first? ‎‎The Devil’s Debt is a dark, addictive enemies-to-lovers romance with high stakes, forbidden tension, and a morally gray billionaire who owns her body—but might just lose his soul to her.
