Query: This is one of the best books ever written

I've read this book twice, and I will continue to re-read it every now and then for the rest of my life. This book is often said to be a deep work of philosophy, which it is; I would like to add that this book, for me, is *a real page turner*. Why? Because I love the heroic characters. Read it for yourself, and see if you share their exalted sense of life.
