My favorite fan fiction is Dreaming of Sunshine, by Silver Queen.

But there’s also

The Howling Wind

The Girl from the Whirlpool

Black Cloaks, Red Clouds

Ibiki’s Apprentice

The Sun Soul

In The Box

The first five are Naruto Fanfics. If you’ve never watched Naruto the only one you’ll have problems with is Dreaming of Sunshine, the following three diverge from Cannon quite a bit, and tell their own unique stories that completely surpass the cannon. I highly recommend them, as they read better than some books I’ve read. Ibiki’s Apprentice is a cute one chapter short, you’ll find it funny.

The Sun Soul is a pokemon fanfic that once again diverges from the cannon quite a bit, I was a big fan, but it’s been a while since I’ve read it.

In The Box is another once chapter short, it’s a Firefly fanfic, it’s cute and funny. If you don’t like it, I don’t like you.
