What did Beth volunteer to do? She was about to drive a semi-tractor-trailer rig across the country. But there were no maps, no diesel, no communication, and no truck stops.

Discovery in Sunshine is a story set in a period of postapocalyptic recovery from volcanoes, floods, fires, and loss of cities and lives within western North America. Her family had developed a better way to collect, store, and save solar power to effectively run heavy transport trucks. Their company needed to prove the effectiveness of this development by doing a test-drive across parts of the country without other fuels. They installed their technology on a truck and trailer that would carry food and medicine. They convinced groups engaged in the transportation industry to support this test. The test would be a trial run from Canada to Mexico by women and men in a semi-tractor-trailer rig mapping roads and finding what cities and peoples had survived. They were without knowledge of what they might encounter and how well this technology would serve them over a month's time. This travel route was without communication, a power grid, or seaports to supply goods. They had hope, grit, and determination. Beth will start on this journey with a physician who wants to find her family. What will they find? What impact can they make?
