The Nine Types of Leader by James Ashton

The introduction is sort of interesting. It is usually used to set the premise of a book, to set context for a story, or to give history as to why the author is an expert on the subject. And oftentimes an introduction is written by someone who is not the author because heaping praise on the following material can come across as somewhat... well, as bragging. And this introduction sure did. There is a LOT of name-dropping in this intro and in the rest of the book. The author has certainly interviewed and been in contact with a lot of people whose names are recognizable. 
I wish there had been more about why these 9 types had been chosen. Usually, with nonfiction, I enjoy seeing the scientific reasoning behind why specific categories were chosen and this book definitely doesn't have that. It is interesting that the author actually makes a point of saying that he didn't want to write "another academic study of leadership." And Ashton even admits that at least one of his analyses is very subjective Aside from the name-dropping, the author is a good writer and people may enjoy thinking about their own immediate (and not-so-immediate) leaders and categorizing them.
