      Fourteen years old Ethan Cosgrove lives on a very large farm in West Virginia, USA. Because the farm is so large, several families work on it together. Each family has its own small house on the farm, and in total there are ten children and teenagers, including Ethan. They never go to school. Instead, they have lessons at home, or at the home of a neighbor.

The students’ parents teach lessons. Students who are in the same age learn together, so he does not study with his little sister. Some of subjects that they study are the same as the ones in normal school, but they also go outside to learn. For a Science class they might go into the woods, and for Math they may visit a local business. Another difference is that students can ask the teachers for lessons on subjects that they are interested in.
