I recently found out about this site and it really spoke to me, I hope it does the same for you. So what are the 5 books I would pick, have you any idea how hard that is, just 5 books! OK, here goes, my five are;
The Thorn Birds
The Clan of the Cave Bear series
5 People you meet in Heaven
There, but I have a few more I will share as a comment since I was only to pick 5, good luck in your list!
