If your favorite phrase of the century is, "Mom, you're the BEST!" then this book is a "gotta have" for your 13 year old daughter. Kate received this book for Christmas (2011), and now, not quite a month later, the pages are dog eared and worn. She has whiled away long winter afternoons gazing at the pictures and memorizing the facts about Justin. It was the perfect addition to her Justin collection of posters, music and magazines. Don't try and understand; just buy it, and you, too, can hear the words, "Mom, you're the BEST!" Very inexpensively priced, and as always with Amazon, the best service imaginable. It's a win/win.
