I live close to Colonial Williamsburg and have an avid interest in Revolutionary War history. This book was a fascinating addition to my knowledge. The Frenchman's Map is one of the best pieces of evidence of how Colonial Williamsburg was laid out during the War. It's precise, labeled, and detailed - and yet, so little is known about it. Even after extensive research, the only question answered was the date - 1782. The rest remain speculation as best. Simpson does an excellent job of moving the reader through the history of the map - including detailed facts about how the Colonial Williamsburg Foundation studied and explored this map. This is a slim volume, but has a lot of information - including colored pictures of many maps. The prose is complex enough for an adult, but would be manageable for a child if they were a strong reader. I recommend as a fine addition to anyone who enjoys Revolutionary War history. ( )
