Hearts and Heirs

One princess. Two worlds colliding. Three days to save a crown. Kyle Carter—brilliant doctor and the newly discovered son of energy titan Grant Harrington—never planned on royal politics. But when the woman he can’t forget appears with danger at her heels, keeping his distance stops being an option. But that’s only where their problems start. Natasha of Belvaria has been hiding in the U.S., dodging a coup that would steal her birthright. To stop it, she needs Kyle to attempt the impossible in a secret palace lab: bring her father back before the kingdom declares him dead.

One crown. Two hearts under fire. Three enemies who would see them fall. Kyle never imagined marriage would come with assassins, bombs, and back-room politics. But as the son of billionaire Grant Harrington—and now the husband of Belvaria’s queen—he’s squarely in the crosshairs. Natasha has claimed her place as Queen Regent, but her victory is fragile. A ruthless brother, a manipulative mother, and a divided council threaten not only her rule but her marriage. Every choice could strengthen her kingdom—or destroy the man she loves.

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.
