Recommend here books that's worth every moment reading and how you felt about it.
Khaled Hosseini The Kite Runner is one of the best books I have ever read.
Also, AThousand Splendid Suns from the same autor.
Depends on what subject you like. For sweet/ basic aspect, you can read <Little Prince>, for adult/relationship aspect, you can try <Men are from Mars, women are from Venus>, for travelling aspect, just choose a book about the place you look forward to.
