Raymond Feist's books have kept me entertained since my childhood. If you are a fan of fantasy books then you have to check out his work. Here's some info: http://www.crydee.com/
You can easily pick up the first book on Amazon or a local used book store for dirt cheap and I promise, once you start reading the series you won't want to stop until the end. He started this series back in 1982 and the last book in the series just came out not to long ago (if it's out already).
I've read all the way up to the first book in the last series and, as of right now, I'm re-reading the series. Has anyone else read any of his work? You will want to read them in order because some of the character appear throughout the entire series. Some character die of old age but some of the magicians (also one of the main characters) is still alive. This series has action, magic romance and is one of the best read's a sci-fi fantasy fan could ask for.
the Discworld series is brilliant, especially Night Watch :]
i also love the Witcher series of books. here's a copypasted paragraph or two i wrote to kitty about them:
"...you should check out the witcher books. they're not entirely translated into english yet, but you can find mobi or epub versions of The Last Wish, the Blood of Elves and The Time of Contempt *shifty eyes* you know, around. and there are *tilts head* mm, fairly good fan translations of the other books from polish into english. you can probably skip straight to Blood of Elves and then backtrack later, tbh.
anyways, the reason i think you'd like them is they're dark/sort of low fantasy with a postmodern touch. kind of like a way better shrek with lots of fvcking and swearing and emotion and racism and murder, i guess? also, in addition to the titular witcher, there's a second main character, his adopted daughter, sort of, Ciri, who comes of age over the stories, and is probably one of my favourite characters ever.
oh also you like cosplay right. here's someone cosplaying her and another character
