I am a fandomer of many I read many series, and watch tons of shows, but, be warned, once I start, I can't stop. Now, let's get down to business. My main fandoms are Percy Jackson, Harry Potter, Maximum Ride, Kingdom Keepers, The Avengers, and The Lunar Chronicles.
If you don't know any of these series, please read them, for they are phenomenal. BTW, I am also a little insane, (what fandomer isn't?) and you have been warned.
