Sounds f*cking cool! I would read that book! I want to read that book!
I love dystopian settings in books. By any chance, is it targeted towards a YA audience?
Yep.
Although the main character is 36 yrs old, he's a bad boy sort of guy and has a sarcastic and witty temperament. He's quite foul mouthed as well and not politically correct at all.
There's a lot of action as he travels on the surface, evading rogue vandals that loot, torture and kill people. But he interacts with all sorts of people underground, where he resides in one of the millions of sheltered cities.
