by Harper Paris, Illustrated by Marcos Calo
Ethan and Ella are twins who travel around the world with their parents. Their mother is a travel writer and their father, who was a history teacher, homeschools them. In this story, the family is in Paris. The twins are in the Louvre, a famous museum, when a painting is stolen. They end up solving the mystery while visiting a secret crepe shop.
This is the third book in the series. The family goes to many different countries, and the stories are sprinkled with facts about the country, famous landmarks, cultural references and a little bit of the language of the country. In the back is a small glossary of foreign words. This is one step up for the Magic Tree House crowd, but the text and the margins are large. The story is fast-paced with lots of dialogue and a pretty decent mystery.
