Well, seeing as I am almost 19 and I am female, i can give you a few that i enjoyed.
Robin Cook - Abduction
It's like this cool book about Atlantis and shit... it was just ... i dunno, realy really awesome.
Robin Cook - Coma or Mindbend
I don't know about anyone else, but I like medical sci-fi, which is mostly what Cook writes (as he is a doctor). Coma is about, well, these people who go in for surgery and end up going into a coma, and this girl who tries to figure out how they go into this coma. Mindbend is ... well.. its about this company who is brainwashing their employees (OB-GYN) to give abortions so they can do testing on the fetus' for their products...
Goethe - The Sorrows of Young Werther
It just... sucks you in. I had to read this for my German History class, and basically, its set in old Germany, and this guy, Werther, is an artist who becomes completely infatuated with this girl, who is getting married to another, but she totally leads him on... anyway, it leads to his demise and its just an all around fun book! Hyok!

Okay, Lindsay, are you forgetting that I was a professional twice over - an analyst and a therapist. The world's first analrapist.
