What Book is It?? #9

I wonder if you can guess this quote: beginning or ending paragraph from a book. Suggest the book and author.

Clues- The author is a man, he writes young adult and adult thrillers, this book is #1 new york times bestseller, and this book has sold over 150 million copies.

"The funny thing about facing imminent death is that it really snaps everything else into perspective."

Any Suggestions??
