Ok, its ages 15+ but.. who cares??
Well, anyhow, its about a girl, Haruhi Suzumiya, who likes aliens, espers, timetravelers, and sliders. She has no interest in ordinary humans. She is described as really pretty in the book. She would be really pretty and popular if she wasn't always frowning with a sour expression and giving one answer responces. She won' t reallly have an actual conversation with anyone. No one seems to really understand her. Then she opens up to Kyon.
Kyon is a sarcastic guy who has many different emotions and sides to him. He is just a normal kid who used to think that aliens and epers and all that were real, but then stopped once he went into middle school.
They form the S.O.S. Brigade which is a club that is actually rather confusing....
If you are interested, I could probably find a link online, or describe the cover to you so you could buy it! Just ask.
