One of the things I love about traveling is getting a good sense of the history of a place I'm visiting. I bought "Flight of Bonnie Prince Charlie" in anticipation of a trip to Scotland, and it was perfect for that purpose. Although it provides an excellent history, it seems designed for the visitor; it's equal parts travel and history.
This book gives a day-by-day description of the Prince's 5 months in hiding from the British before he was able to escape to France. He trekked hundreds of miles on foot, in disguise (once, famously, as a ladies' maid!), sometimes passing within earshot of the soldiers hunting him. The book is liberally illustrated with modern photographs of the particular glens and mountains Charlie passed by, as well as reproductions of painted portraits, etc. of the main participants.
Even better, each part of Charlie's escape is accompanied by a detailed map showing where he was on almost a night-by-night basis. In the appendix there are even driving directions and a list of relevant places for tourists to visit.
If you don't know the story behind Charlie's daring escape, you could not start at a better place.
