Born with strange skin blemishes, Marcus Azure lives in constant ridicule. Abandoned by his parents and shunned by his village, Marcus finds hope in a better life by joining the military at the age of sixteen.

But his life quickly turns chaotic when a mysterious group of assassins attack his village. Desperate to prove himself, Marcus embarks on a quest of revenge and encounters Sinclair Bonet, a rogue queen who reveals that Marcus's skin blemishes are a sign of great potential. She offers to train Marcus, but in return he must join her in the great war against the Divines-powerful humans with abilities to manipulate metals, harness the wind, and turn flesh to ash.

But when Marcus uncovers the truth about the attack on his village, he questions everything and must decide whether to fight against the Divines or betray the very people he loves most.

In the end, the final decision may not rest in his hands...
