I bumped this up from the comments. DeVito has a novella in an ebook.
Buy it now!!
'In a strange, violent, debauched future, an assassin confronts a new technology that enables immortality, destroying the value of death, and he begins a quest for oblivion, so goes "Final Kill" by Chris DeVito.
I haven't read it yet, but I know DeVito and if anyone can do strangness, violence and debauchery, it's him!
