They Call Me An Angel (en Inglés) - Autumn Wolff

Dysella Thorn is a half-angel/half-demon hybrid just trying to keep her sanity in the apocalypse. Everything went to shit when God and the Devil decided to take each other out in one final Duel. The shockwaves from their combined demise destroyed most modern technology across North America. Following a mass exodus of people and supernatural beings, those who remain behind now live in a quiet, dark continent.

Amidst all the murder, mayhem, and magic that come from living on a semi-lawless frontier of ruin, Dysella spends her days drinking and trying to forget in a tavern hidden by her fae girlfriend's enchantments. She pays her rent in love and the occasional good deed, but everything changes when a stranger shows up asking Dysella to help retrieve something.

What should be a simple and straightforward task turns into the biggest mess of Dysella's existence, and she'll need to put the pieces of her life back together if she's going to survive.
