'What Is the Panama Canal' was informative and a quick read, and it had some interesting details that it pointed out, and even one that was funny towards the end, at least in my opinion. It wasn't my favorite, though that isn't too surprising considering that the genre of the book isn't the thing that I seem to run towards like my life depends on it. If this is the sort of book you enjoy, it is informative, and not too dry, something pretty crucial for me in books about historical events and characters.
