Shadow Sword Trilogy- Phantom Princess

Who would you become if your worst fears came to pass? Morrígan Feighlí is lost. With her closest friends refusing to acknowledge her, she leans heavily on her new relationship with King Dàibhid and on her purpose as a sellsword. But even her purpose is fragile as her old life looms closer. And if it finds her, it won't let her out of its sight again. With his subjects scared, displaced, and held hostage, Dàibhid blames himself for the damage his country has sustained. But before he can enact plans to reclaim Cunlaran from the Exiles-and fix his mistakes-a familiar face from his and Morrígan's pasts arrives at the Stone Fortress. While they could be Dàibhid's salvation, he fears they are certain to be Morrígan's downfall. With the odds stacked against them, more traitors rise. If Morrígan and Dàibhid can't learn to reconcile their fears with their hopes, neither Cunlaran nor their hearts will survive.
