Heir of Light — Jill Williamson

Sir Rigil Barak came to Land s End expecting a routine mission: investigate some rumors, spy on some nobles, and above all, play the perfect knight. Instead, he is reunited with his less-than-shining past the same past that has kept him on the road for years, fleeing his noble father's scorn and grieving the woman he thought dead. Until now. And if she's alive, he'll do anything for a second chance to save her. Years of captivity has left Sethe with one rule: never be trapped again. Except, to keep that rule, she'll have to ask for help from the thief who broke her heart, because Sethe s old captor is hot on her heels with a new invention that could turn her into something worse than a prisoner. He could turn her into a weapon. Fortunately, Rigil and Sethe always did know how to pull off a heist and if they can steal the enemy s deadly new weapon, they can save the kingdom
