Godkiller (The Fallen Gods #1) by Hannah Kaner

Regarding location - Google will may say that the Hugh is closed, but it is not. We will meet inside the food court and there will be sign holders on the table with the book cover on it.

From Good Reads:

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.
