The Gutter Prayer (The Black Iron Legacy #1) by Gareth Hanrahan
A group of three young thieves are pulled into a centuries old magical war between ancient beings, mages, and humanity in this wildly original debut epic fantasy.
Enter a city of saints and thieves . . .
The city of Guerdon stands eternal. A refuge from the war that rages beyond its borders. But in the ancient tunnels deep beneath its streets, a malevolent power has begun to stir.
The fate of the city rests in the hands of three thieves. They alone stand against the coming darkness. As conspiracies unfold and secrets are revealed, their friendship will be tested to the limit. If they fail, all will be lost, and the streets of Guerdon will run with blood.
The Gutter Prayer is an epic tale of sorcerers and thieves, treachery and revenge, from a remarkable new voice in fantasy.
