I don't suggest the Twilight series (Sorry, but I noticed some flaws, will probably get flamed for that)
1. Little Women
2. Anne of Green Gables series
3. Harry Potter series
4. Rebecca by Daphne Du Maurier
5. Jane Eyre
6. Wide Sargasso Sea
7. Count of Monte Cristo
8. Anything by Mark Twain
9. Anything by Amy Tan
10. The Shopaholic series
11. Pride and Prejudice
12. The Witching Hour series
13. Interview with the Vampire
14. Atlas Shrugged
15. Scarlett by Alexandra Ripley ( sequel to Gone with the Wind, hated it as a sequel but it was a good story on its own.)
16. Carmen by Bizet ( this is an opera but there are books with the opera text,lovely.)
17. Watermelon by Marian Keyes (SOOO funny)
18. The Casteel series by VC Andrews ( yes. I know...but the Casteel series is the best)
19. Angela's Ashes
20. Any biography about movie stars back in the day. Like Marion Davies, Lana Turner, these movie stars are MUCH more interesting.
