At first i didn't know there were any books. I watched the movie and went on with my life, one day i decided to look it up and i found the books, i read them on an e-reader and it was the best decision i have ever made, i cried so many times, wether tears of joy or sadness i cant tell but i can tell you that laughed just as much. I definitely recommend this series of books if you want to experience love with all sides, the happiness, the sadness and the rush.
