How to Succeed in Evil is the story of Edwin Windsor, Evil Efficiency Consultant. He's like Arthur Anderson for Supervillans. A novel by Patrick E. Mclean (the guy behind the Seanachai podcast). The novel (promo mp3) will be available March 16th, but the entire thing is already available free in audiobook form as itunes files (zipped) (err..should be eventually but dropbox was giving a 500 error when I tried it) or mp3/stream. There is also a promo comic (pdf) illustrated by Nicolaus Rummel.
The Raw Shark Texts (spoilers if you poke around) is a novel about conceptual fish by Steven Hall that is rife with typographic gimmickry and has an ARG-like element to it. [more inside]
