I've read Windcatcher with four or five classes of fourth graders. They all like say they like it, and they aren't afraid to tell me what they think. Tony Souza is a boy we all can identify with. After we learn the sailing jargon, we get involved with Tony's adventures. We also flash back in time to the Revolutionary War era to Captain Ezra Littlejohn and the payroll ship that sank in the area where Tony's grandmother lives. Will Tony find the treasure, and what kind of trouble will he encounter trying?? Good book.
