Joe Abercrombie - lots of violence, dark humor, he is the best
Paul Kearney - feels real, it could have happened
Brandon Sanderson - a bit more lightweight than the above 2, but very entertaining with some humor
Brent Weeks - very entertaining stories
Alastair Reynolds - he is the best contemporary scifi writer imho, just avoid "The Prefect"
Liz Williams - not the usual scifi themes and this makes it very entertaining
Vernor Vinge: Deepness duology is fantastic
Douglas Adams: he is the best in humorous sci-fi
