I'm 51 years old now but i first read this book when i was in high school. It is SO SPINE-TINGLING SCARY that i had nightmares for a WEEK afer i read it! BUT, i have read it 6 more times since high school and each time i just deal with the nightmares because this book is BY FAR ONE OF THE BEST I'VE EVER READ!!! IT'S A MUST-READ, MUST-HAVE BOOK!
