My only criticism is: for as thick as this book is, I would have liked to hear more about Paine's relationship with all of the great historical figures he knew, since that is one of the things that makes Paine so interesting. Also Keane has a tendency to interject his own views into the narrative and sometimes it becomes hard to discern where Paine's views end and Keane's began.

Otherwise it was a first rate biography. Keane is a great writer and the book reads more like exciting fiction than the usually dry history.
