Lost Cause - Z. J. Cannon - Bog

Humanity finally has a hero who can stand up to Hell.
It's my job to stop her.
Guess that makes me the villain.

Ever since Heaven lost the war, the forces of Hell have treated my city as their playground. One human is finally pushing back. With the power of a saint's relic behind her, she's bringing light to Jarvis's dark streets, one dead demon at a time.

But not every demon is one of the bad guys. Some of us just want to live our lives in peace. And if I don't stand up for the ones who can't defend themselves… well, who else is going to care what happens to a bunch of monsters?

I wish I'd never asked. Because now none other than Vekaniel is sitting in my office, offering to join forces to protect the good demons of the city.
Yep, that's right: the scary-powerful fallen angel. My former ally in the war against Heaven. The one I went up against a few months back, and barely came out alive.

She swears she's on the straight and narrow now. We'll see about that. But the fact is, I can't win this alone. I need help. The kind only a dangerous, devious, and maybe-reformed fallen angel can give.
