Do you have one book that you can read over and over again without fail? There are a few Stephen King novels that I don't seem to get tired of (Bag of Bones, Eye of the Dragon, etc.), but the one that stands out the most is one that I read when I was even younger.
I was going through a stage when I would read a book in a matter of hours. There were a few years in middle school when I would go through two or three books a day. Now, these weren't Dickens or Hemmingway, mind you, because that's never really been my style. I read most of the Sweet Valley High books when I was ten, and then moved on to scarier things - you know, R. L. Stine and then to John Saul and Anne Rice. (Those took me slightly longer, which is what I was looking for - I hate the feeling I get when the book is ending and I won't get to spend anymore time with the characters inside. Since then, I've learned to read a few minutes a day and stretch things out a little.) I was somewhere between R. L. Stine and John Saul when I found L. J. Smith's book, The Initiation.
I can't remember what year it was, but it was the summer time. The third full week in July, the week that my family and our friends go camping by Lake Metonga. We were picking up some last-minute supplies at Kmart, and I ran (as always) to the book section to pick something out. I wanted to take something with me to read. I just knew the fifteen books from the library weren't going to be enough. I don't think I touched those other books for a few days. I read this book, and then I reread it, and then I read it again at least three times. I couldn't wait to find out what would happen in the next book. It was torture, looking for The Captive everywhere my mom would drive me, trying to find it somewhere so that I could keep reading... I finally settled on reading the third book second, because the second was nowhere to be found. Confused? Sorry.
I found these books in a box in my old bedroom on Friday night, and I've read a book a day since then. Well, a book a few hours - I wasn't reading all day long - but I'm finally finished. They're just as good when you're twenty-six as they are when you're twelve.
If you can, find them and read them. It doesn't take very long, and it's worth it.
