Some hilarious internet pranksters have released a fake romance novel on iTunes, managing to get the erotic fiction up to #4 in the iTunes chart simply by it looking a bit like senior citizen wank read of choice 50 Shades of Grey.

The crowdsourced book, which calls itself The Diamond Club: A Novel and is written by the non-existent Patricia Harkins-Bradley, costs 99p to purchase, with proceeds going to fund some sort of nerd gathering by joke organisers NSFW Show. The iTunes description promises hormone-crazed readers "an exotic gathering of the Bay Area's most attractive and interesting people, from angel investors and airline pilots to world–famous chefs and dubstep artists."

It would appear to be a roaring success already, as the fake novel, complete with five-star reviews from punters in on the joke and happy to blow a quid on infuriating 50 Shades fans, is already at #4 in the Top Romance Books category on iTunes. [iTunes via TNW]
