Loner by Teddy Wayne

David Federman is a freshman at Harvard when he meets the beautiful Veronica Morgan Wells. He instantly becomes so infatuated with her that he is willing to do anything to get her attention.

This book was so disturbing. I could not put it down. If you've ever been stalked before, this book will feel familiar. Yucky! Disturbing but fascinating, and really well done in capturing the ick of stalking.
