These books may not be long, but they contain great adventures. They're more Harry Potter with a scavenger hunt. The 2 main characters, Dan and Amy, travel around the world with their au pair (babysitter) to compete for $1,000,000. I would have to give this book a 4 out of 5 stars, because whenever they are in a death situation, it's kind of obvious they will live, because there are other books to the series.
