GodKiller by Hannah Kaner
Three characters who don't get on and don't trust one another. A quest with high stakes. Magic, tension and mystery. Incredible world building. This fantasy book has everything. I adored it.
From the back
You are not welcome here, godkiller.
Kissen's family were killed by zealots of a fire god. Now, she makes a living killing gods, and enjoys it. That is until she finds a god she cannot kill: Skedi, a god of white lies, has somehow bound himself to a young noble, and they are both on the run from unknown assassins.
Joined by a disillusioned knight on a secret quest, they must travel to the ruined city of Blenraden, where the last of the wild gods reside, to each beg a favour.
Pursued by demons, and in the midst of burgeoning civil war, they will all face a reckoning - something is rotting at the heart of their world, and only they can be the ones to stop it.
