What makes this book?

Personally, I think what makes this book astonishing is the fact that it's so real and relatable. Holden has the same mindset as so many other young teenagers have these days, you see the progression through the book as Holden goes through puberty and matures into a young man. Along the way he goes through realistic experiences that any other average teenager would. Holden Caulfield is so easy to relate to that you tend to want to follow in his footsteps and learn how he handles situations, even if it doesn't work out for the best. He teaches you that not everything is perfect in life and you're going to have times in your life where you feel nothing but trapped and misunderstood as a kid in this world. He always over analyses things, people, and situations. He does what he wants to, which i think a lot of people wish they could. Holden is sarcastic in a way that makes you think. Although I do really hate endings that leave you hanging, I think JD Salinger did it in a way that seriously makes you think about the book. He also lets your imagination do a lot of the work. He lets you wonder why and how Holden got sick at the end of the book, but that is where your imagination picks up the rest.
