Cast Me North, I Came Back a Queen

On the eve of her wedding, Seren discovers her fiancé Caelan—the South's most powerful heir—only married her to shield his true love from a deadly curse. Betrayed and heartbroken, she swaps brides and flees north to a barbarian warlord she's been told is a monster. But the North is not the hell she expected, and her new husband is not the beast they claimed. As Seren transforms from sacrificial pawn to a queen of the frozen wilds, Caelan uncovers the devastating truth: she was always his real savior. Now he must cross a war-torn continent to win her back—but she's no longer the woman he lost.
