Genre: Early Chapter Book
Review:
Very cute story showing that cheating is no way to win. It would be a great lesson to elementary aged children. Definitely appropriate for a 2nd grade chapter book although some of the language might be more appropriate for late 2nd grade reading. Interesting plot and some funny moments.

When international detectives, Max and Maddy, tackle the Bursting Balloons mystery, they're onto a tough case. Someone wants to sabotage a hot-air balloon race across America and they'll stop at nothing - bursting balloons, stealing sandbags, breaking baskets and guzzling gas!
