The hardest part about this journey around the world is putting the book down. The vocabulary is quick and accessible, designed to keep the action flowing fast and loose. Once the Cahills arrive in France, there are a few small lines of dialogue in French, but they won't have you saying sacre bleu! and clutching your head in pain. All the important ones are translated for you. Maybe you'll even learn a few helpful phrases. And finally, while there are a few brain-bending puzzles, like the French phrases being translated, the puzzles will be solved for you if you can't figure them out on your own.
