For those of you who haven't been introduced into the bizarre world of the Cthulu mythos, Kuro5hin comes to the rescue with a brief introduction. Great pulp horror, wierd and Victorian and completely different than other types of horror that most people are familiar with. Much more psychological, with characters that literally lose their mind when they see things that the human mind can't understand or accept.
In the interest of full disclosure, this IS coming from someone who bought his wife a stuffed Elder God.
