I loved this book as a kid and just re-read it in a single afternoon. Keeping in mind the social mores of the time it was written (very early 20th C.) and that problems were different then than now, it still is an outstanding story for young people and can be seen as an opportunity for a discussion about how times have changed.Bert and Nan, and Freddie and Flossie, the two sets of Bobbsey twins, deal with bullies, scary situations, etc., and learn lessons about kindness and good behavior through all of it. This is the first of the Bobbsey Twins books, many of which I was delighted to find available via Project Gutenberg.
