The factor that the Nancy Drew books deserve so much merit for is their ability to captivate a reader of any age. I have been reading the mysteries on and off for at least 6 years now, and I have been intrigued just the same all along. As I recently decided during English class, the most important thing about good writing is its ability to keep the reader interested. I know that a book is well written when I do not notice irritating or strange writing techniques and when I want to read it for hours and hours without putting the book down. Back in the good old days of 6th grade, my parents busted me night after night reading Nancy Drew under the covers with a flashlight.
From the Mystery of the Glowing Eye to the Clue in the Crumbling Wall, every Nancy Drew Mystery book has a captivating can't-put-it-down storyline, involving many familiar characters and introducing new ones each novel, some of whom stay in the series and some of whom only stick around for one book. These characters are well described, and I can always picture them in my mind as I am reading. I have never been able to fully predict the novels either, because they always take sudden and unexpected turns, which enrich the stories greatly.
