This was actually a lot more difficult than I thought it would be!! I went through the books that I've read, but also through the list to try and not pick books that have already been listed a few times. Here's what I came up with:
Wuthering Heights by Emily Bronte - This book restored my love of literature as a high school senior. But also because it is the most romantic book--tragic, but who could forget those harrowing words, "I AM Heathcliff."
My Sister's Keeper by Jodi Picoult - Picoult always shows all sides to every story, and this one I could especially relate to as my younger sister had a kidney transplant 5 years ago (when she was 18). Although I wasn't in exactly the same circumstances, I could relate to Kate's siblings.
Anne of Green Gables by LM Montgomery - Because I grew up in Canada, and when I was little I wanted to be Anne so badly. I loved her--still do. Happy Canada Day everyone!
Bridget Jones's Diary by Helen Fielding - Because I, like Bridget, obsess about strange things, fantasize about what could be, and over complicate things in my head. I love Bridget--she is my hero.
Mrs. Dalloway by Virginia Woolf - Her female characters are all so different, but I think that everyone could find a woman in this novel with whom they relate to. And besides, I think we've all had days like Mrs. Dalloway. (If you've read this and like it, you must read The Hours by Michael Cunningham).
