The last few years, i´ve read fanfiction more than anything else.
Like:
http://www.fanfiction.net/s/4155819/1/Fifth-Column By EvilAuthor, this is a crossover between Battlestar Galactica and Battletech.
http://www.fanfiction.net/s/5175006/1/Divine-Blood By Thrythlind, a massive multicrossover using Ranma 1/2, Oh My Goddess, Full Metal Panic among others, that is so good the author has since started rewriting it into an original story, first book of which can be bought (well worth it) for $1-3.
http://www.fanfiction.net/s/5612465/1/The-Prototype By DelVaro, an interesting story based on Elfen Lied (not for the faint of heart). Just wish he would get on with the sequel. ^_^
http://www.fanfiction.net/s/5353683/1/T ... -Who-Loved By Darth Drafter, a crossover between HP, SM and R1/2. The cursed springs of Jusenkyo has a very "interesting" interference on the Harry Potter universe. Should be read, if nothing else just to find out the fate of mr big bad Voldy... *lol*
http://www.fanfiction.net/s/6940744/1/A-Teacher-s-Glory A Naruto-fic by Larry Huss. Based on the stupid comment by Kakashi "If you don't come at me with complete dedication, with the willingness to kill even, you will certainly fail"... And so they do, one dead Kakashi later and...
http://www.fanfiction.net/s/3566724/1/T ... -of-Nerima Claymade´s R1/2 and SM crossover is, amusing...
http://www.tthfanfic.org/Story-28693/ke ... dariam.htm Kedrann´s rewrite of "Stars Reborn", SM+Buffy+multicrossover with some very interesting twists.
http://www.tthfanfic.org/Story-4305/Arj ... unrise.htm One of the hoard of Buffy Halloween fics, this one of the very few that uses Dawn as the main character. She dressed up as Kirika from Noir, a nice choice.
http://www.fanfiction.net/s/7178946/1/A ... Switchover Cun is one of few who writes good "Railgun" fics, this one based off taking a cliche and playing with it for fun. Mikoto and Kuroko gets to make a little switch, oops.
