Four Seasons of Land

The world of the Four Seasons is a lot like earth. The only difference is that their are only five different continents. Four of the five hold only one season. Winter, Spring, Summer, and Fall. The fifth carries all of the seasons. That one continent is kind of like the homeless of the world. Every year, all the 18 year olds get put on a large train and sent onto a month long "Trial" of the four seasons.
