I was a medievalist myself and think this book does a nice job of giving a picture of overall life in Europe circa 1100-1400. High school readers (and we adults) should be quite interested in the details of how hotels and toilets worked (or failed to) in those days. And the topic, pilgrimages, gives a useful way into discussion of the important role of the church in everyone's life while allowing sidelights into the life of a farming serf, say. It's not an extremely scholarly job (sourcing is entirely to other secondary works, and those more in the Barbara Tuchman line), but it does quote the right medieval voices lifted from those other history books, and it's smoothly, cleanly written at a level appropriate for high schoolers. Too bad the pictures aren't in colour.
