Alchemist by Paula Coelho. A wonderful read.
Well, I have found best ever book "Milestones" by Sayyid Qutab in Urdu language but is also available in English as well.
For me the best book, or perhaps I should say, "most important book", although I have my doubts as to whether I can inspire you to read it, is "The Unspoken Sermons of George MacDonald.
The reason for this is that, reading this book, I realized for the first time that it was not necessary to believe absurdities (as I saw them), or fall in line with any established dogma, to have faith. More specifically, George MacDonald demolished what I had always thought "Christianity" was, including the idea of an eternal hell--and this was important, as for me, the concept of an all-powerful yet all-loving deity sending masses of people off to an eternal cosmic torture chamber was both horrific and senseless.
The book is online, free to read, at Project Gutenberg.
I have two! The first is The Secret by Rhonda Byrne It was an inspirational book, and filled with a ton of make you feel good ideas. Then there is The Guardian by Nickolas Sparks way opposite as my first choice, but I love a good love story and this book had that and some.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
