The Adulterants by Joe Dunthorne

Ray is not a bad guy. He mostly did not cheat on his heavily pregnant wife. He only sometimes despises every one of his friends. His career as a freelance tech journalist is dismal but he dreams of making a difference one day. But Ray is about to learn that his special talent is for making things worse.

Brace yourself for an encounter with the modern everyman. Enter the world of ironic misanthropy and semi-ironic underachievement, of competitively sensitive men, catastrophic open marriages, and lots of Internet righteousness. With lacerating wit and wry affection, Joe Dunthorne dissects the urban millennial psyche of a man too old to be an actual millennial.
