I recommend reading ttyl, ttfn and l8r, g8r. It is a series by Lauren Myracle. They are different than other books in that it is told from instant messages and texting. They are about three girls in high school and what happens to them during the three years each book is one year. They are fun books to read and they are hard to put down. I was kind of bugged by the fact that I didn't know what was going on in their school unless they explained it. But I really liked them and have read them several times. My mother has read them as well and enjoyed them too.
NOTE: there is language and sexual content.
