"The Hammer Falls", by Travis Heermann
A novel, set in a cyberpunkesque dystopia, where corporations owned by the different OC syndicates run the country, where laws are just meaningless words on paper (unless the corps want them to mean something), and in which the poor masses are kept entertained by watching cyberenhanced gladiators/wrestlers, that step into the ring for a kill.
But dying is ok - as long as you don't loose your head (literally and figuratively), and you or your promoter can afford the regeneration.
Heck, if you die often enough, it can even boost your name recognition - just ask Horace "Hammer" Harkness about it...27 deaths racked up so far, and still counting.
But, of course it sucks, when the regen-process is rigged by money-craving mobsters...
I'm about two thirds through right now, and so far I like what I read.
It's no "great literature" - but it's entertaining.
Recommended, if you're into cyberpunk and similar stuff.
