That's hard cause none of these authors are my favorites, but they've all written books I like:
F. Scott Fitzgerald- The Great Gatsby
Ray Bradbury- Fahrenheit 451
Paulo Coelho- The Alchemist, Veronika Decides to Die
Mitch Albom- The 5 People You Meet in Heaven, Tuesdays with Morrie, For One More Day

So I'll go w/Sophia's choices since I've read and enjoyed more of their books. Even though all of Albom's novels make me really emotional and cry... but still great books.
