The Devoted Lands was once home to many gods: Salt, Stone, Storm, Green, Shadow. Now, after centuries of devastating wars, only Tempestra-Innara, the Eternal Flame, remains.

Conscripted as a child, Lys, potentiate of the Dawn Cloister, is outwardly a loyal servant to her goddess. If she harbors impossible dreams of deicide, that's her business. But 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 that holds the power to kill a god. Annoyingly, she's not alone. Paired with Nolan, a potentiate from a rival cloister who is as pious as he is determined, Lys must feign devotion if she hopes to keep her own heretical thoughts hidden and god-killing ambitions within reach.

As they pursue a dangerous network of heretics linked to the assassination, Lys uncovers a world brimming with more possibility--and peril--than she ever anticipated.
