We have many of the Classical Kids CD collection, but this one is my children's favorite (ages 5 & 7). The story on this CD is a mystery that contains some sadness, clues, dangers & problems to overcome, fun, excitement - and of course great Vivaldi music. Even though my children knew the ending after hearing it the first time, the story & music are so compelling that they love hearing it over and over again anyway. It's one of the CDs I enjoy listening to with them. If you like Classical Kids' Mozart's Magic Fantasy/Magic Flute, you'll probably like Vivaldi's Ring of Mystery (my 5-yr-old thinks the Mozart story is too scary for nighttime, but not this Vivaldi CD, if that helps you guage the 'danger' at all). Enjoy!!
