Well written, ok illustrations, intelligent analysis, useful as a primer on its subject; would have been better if it gave a decent modern map of Alexandria to allow a reader new to the subject to frequent themselves with the layout of the place as being detailed in the text.
Not a taxing book at 200 pages, maybe it falls apart a little after P.113, when it shifts from classical history into the dark ages, where due to the lack of information the writer increasingly has to work with conjecture, too much time of which is taken up with trivia such as 1 or 2 eccentric treasure hunters, modern day Greek politics & obscure bits of masonry. Maybe it also goes on a bit too much about Alexander III's tomb being some sort of metaphysical "idea" instead of an actual site.
If you're new to the book's theme buy a copy, you'll learn something.
