Book excerpt: The thirty-eight volume Judy Bolton series was written during the thirty-five years from 1932-1967. It is one of the most successful and enduring girls' series ever published. The Judy Bolton books are noted not only for their fine plots and thrilling stories, but also for their realism and their social commentary. Unlike most other series characters, Judy and her friends age and mature in the series and often deal with important social issues. To many, Judy is a feminist in the best light-smart, capable, courageous, nurturing, and always unwavering in her true beliefs; a perfect role model. In this twenty-eighth book of the Judy Bolton Mystery Stories, in the heart of Yellowstone Park, at the Dragon's Mouth, Judy finds a vital clue to her husband Peter's bank robbery case and at the same time places herself in great danger.
