3 1/2 stars. Well written, but a little disappointing if you've seen the original videos on YouTube's Eerie Edinburgh. They do better on the screen; the photography is lovely and Mr. Gilbert has a beautiful voice. And having seen them, it's a bit of a letdown to read them.
The author does a great job of telling a story, and includes a lot of historical context. Worth reading, especially if you haven't seen the videos.
