My recommendations are bit different from all of the others:
1. The Strange Case of Dr. Jekyll and Mr. Hyde by R.L. Stevenson (Although a short story but still is the best of my list)
2. The Roots- Alex Haley
3. The Count of Monte Cristo- Alexandre Dumas
4. Lord of Flies- William Golding
5. To Kill a Mocking Bird- Harper Lee
6. Round the Moon- Jules Verne (Better read all his novels)
7. Jurassic Park & The Lost World- Micheal Crichton
8. The Foundation series- Isaac Asimov
