Steeling Light by Evelyn Hart

He’s the son of her enemy. She’s the girl he never stopped dreaming about.

Ainslee’s mission is simple: find Vesta and the most important book in Nyth. She knew it was a nearly impossible task when she left Stormhaven.
What she didn’t know was who would be waiting at every crossroad.
Rhion Rahn is the Prince of Steel, the commander of its army and a brutal mountain of a man. Other than Gethin himself, no one is more feared.
But before he was any of that, he was just Rhion to Ainslee. A boy who was willing to fight a basilisk to save her. A boy who loved long walks and good conversation.
What starts as an attempt to sway Rhion to their side of the impending war becomes something more. Every word he says brings back those childhood memories, and every touch sparks a flame inside her.
But as Ainslee gets closer to finishing her task, loyalties must be decided. Their time together may have rekindled a flame, but can that flame stand against the winds of what’s coming?
