The Malloy girls and the Hatford boys are in constant competition. One of the Malloy girls tries out for the previously all-male baseball team, and another is competing with one of the boys in the spelling bee. They're all racing to see whose bottle (filled with contact information) will travel the furthest down the river. Will it be the boys or the girls who come out on top this time? Look for other books about the Hatford boys and the Malloy girls (this is the eighth book in the series featuring these characters). The Boys Start the War is book one.
