The Lost Reliquary (Divine Thrall, #1)

"The Devoted Lands was once home to many gods. Now, after centuries of brutal wars, only Tempestra-Innara, the Enduring Flame, remains. As a divine warrior, Lys is outwardly loyal to her goddess. If she dreams of deicide, that's her business. When a routine heretical execution erupts into a near-fatal assassination attempt on Tempestra-Innara, Lys sees a glimmer of hope for her freedom. Lys is chosen to hunt down the heretics and find an ancient reliquary with the power to kill a god. Annoyingly, she's not alone. Paired with Nolan, a warrior from a rival cloister who is as pious as he is determined, Lys must feign devotion if she hopes to keep her own god-killing ambitions within reach. But as they pursue the heretics linked to the assassination, Lys uncovers a world with more possibility--and peril--than she ever anticipated"-- Provided by publisher.
