Book Beginnings on Fridays

Leth hesitates at the silent threshold. He had braced himself for confrontation, but the Tariel family chapel is empty.

from The Sword-Witch's Heart by Tavia Lark

Leth is forsaken by both his family and his god who he betrays them for. Desperate for a chance to escape and prove himself, his joins his old infuriating companion 's quest to clean up demon infestation. during the quest he rediscover himself, Evain, and the mutual annoyance grows into a passionate romance.

I really loves characters who rebuild their lives after loss, and banter and flirting, and the romance is both believable and hot.
