Lord of Hell by Charlene Hartnady

I hate my father. At least, I want to. He is an evil bastard. I should hate him. You see, he’s Hades. God of the Underworld. I am his son. I find I desperately want his approval and, at the same time, don’t want to be anything like him. It’s a screwed-up place to be in. And people wonder why I am the way I am.
Hades is despicable.
Immoral.
Cunning.
He’s my dad.
I’m not sure why I keep returning to hell. Why I keep going back to see him. Why I torture myself with his indifference. Am I ever going to learn? It seems not. It’s always the same, just when I think I am dead to him, he gives me another one of his duties. Something easy, he says. Something even I – his disappointment of a son – can get right. I should know better. I should turn him down flat. I can’t!
I do a stupid thing and accept. Now I have to bring a soul to hell. Her time is up. This woman killed an innocent. Fetch her. End her. She’s a murderer. Deserves to spend eternity down here. Only it isn’t as simple as my father said it would be. Not even close.
