Query: Garbage, worst on the subject

This book is a mess. The thesis presented in the introduction is a rambling essay on the importance of followers and historical forces in leadership, which might leave the reader less informed about leadership than before he/she read it. What's worse is that the intro has nothing at all to do with the rest of the book (which is marginal in it's own right). The case studies are way too short and are made even less informative by Wills habit of not even mentioning the leader until five or six pages of nonsense. My overall feeling of this book is that it was poorly researched and badly written. I wonder (in all seriousness) whether Wills knows anything at all about some of the people he writes about. Skip this one. I suggest Lincoln on Leadership instead: it provides the rudiments of leadership with clear, well researched examples.
