An Instant USA Today Bestseller!
A princess desperate to win back the prince who broke her heart follows him to his kingdom’s prestigious military academy—and in doing so, falls in love, saves the realm, and continues to look fabulous, in this delightful debut fantasy.
Domhnall and Clía are an ideal match—or so everyone says. They are prince and princess of neighboring kingdoms. An alliance the gods will smile on. Until Domhnall ruins everything by refusing to propose.
Heartbroken but determined, Clía makes the perfect plan: Follow Domhnall to Caisleán Cósta, the military academy he’s attending. Show she can protect her kingdom. Secure the betrothal. Sure, the castle has a brutal reputation. But how hard can dueling really be?
Warrior Ronan promised himself he’d never lose his focus. He fought and sacrificed for his place at Caisleán Cósta, and he has no time for blonde princesses who waltz into arenas like they’re attending a ball. Even if she and her otter-like pet are… well, cute.
He doesn’t want to be intrigued by Clía. But her hunger to prove herself is something he understands. He tells himself there’s no harm training her. Even if his heart does race around her. Even if Domhnall is his best friend.
But as they say, love is a battlefield—and unfortunately for them all, a very real war is looming on the horizon. It’s a fight that will threaten all their kingdoms… and test all their hearts.
