BOOK 3 OF HEARTS AND HEIRS ROYAL BILLIONAIRE ROMANCE, A CLOSED DOOR ROMANCE SERIES. One vow. Two hearts pushed to the edge. Three enemies left to conquer. For Dr. Kyle Carter, being Belvaria’s newest prince was supposed to be an honor. Instead, it’s a battlefield. His wife’s enemies are closing in, his father-in-law’s crown wavers, and every heartbeat of peace feels borrowed. Princess Natasha Romanov has survived betrayal, exile, and war—but now she faces the unthinkable: to save her people, she may have to sacrifice herself. As her brother’s final coup ignites and old family wounds reopen, Natasha and Kyle must decide whether love can endure when duty demands everything. With danger at the palace gates and treachery in the bloodline, they’ll fight for their marriage, their country, and the forever they were promised. Can love truly conquer a legacy of lies—or will the crown claim them both?
