One of my favorite parts of the book and to me, a very large life lesson is the part when Flick talks about Peter-pan (you'll have to read to find out) and the fact that the Academy resembles a game of chess. All of the students are pawns. Then comes the higher figures up and up until the king, some would say its Flick's father, others Mandel. Overall its Flick"s journey as he becomes a better person that hits right to home, because he goes through exaggerated forms of what every teenager does.
Overall, I would recommend this book to everyone. Great read and inspirational message.
