'Catcher in the Rye' written by J.D Sallinger. First of all, this book has received so many hate reviews but lemme tell you, irrespective of the fact that you may find the story or plot off but the way this book is written, it is one of the coolest ways. Totally informal language throughout with some masterpiece quotes and the one which is my all-time fav "Certain things they should stay the way they are, you ought to stick them in those big glasses and just leave them alone."
