This was quite a fabumouse story! The Thea Sisters, five teen-aged mice from all over the world that are best friends, are all going to Collete's home city, Paris, for vacation. While there, Collete's cousin, Julie, is preparing for her fashion show. However, someone steals her entire collection! It is up to the Thea Sisters to find the culprit and help Julie. While the actual plot is very predictable, the format of the book is very welcoming to beginning chapter book readers. There are bright pictures, bigger font, and different colors and styles of font that pepper the text and make it rather jazzy. Younger readers that might be scared of reading boring black and white text chapter books will welcome the bright words. Another cool feature is that there are informational sidebars about some of the aspects of French culture, which will help the young readers learn about French culture while they enjoy this cheerful mystery. The only fault to me is that at times all of the features, like the colors and sidebars, can be distracting. Overall, this book is highly recommended for readers ages 7-11.
