I enjoy reading Fanfiction.
Especially yaoi stories.
Favorite couples I love to read about would be
KanamexZero (Vampire Knight)
LxLight (Death Note)
SasorixDeidara (Naruto)
TakumaxShiki ( Vampire Knight)
KainxAido (Vampire Knight)

Hmm, when I read real books they would be mostly about Horror, Suspense, Drama, Action and it has to be fiction.
