The Ember Debt

In Ashport, every flame you command steals a piece of who you are. Wren Calloway burns brighter than anyone since the night her brother died in a fire only the vigilante known as the Ashen Saint could have started — and she's sworn to bring him to justice, no matter what she has to sacrifice. But the closer she gets to unmasking him, the more her own missing hours start to look like his crimes.
