I downloaded this before all the drama that began with the silly FOX interview. In my opinion, any controversy about the author's "right" to publish this book is just ridiculous. This is an historical work, not a religious text. Jesus' concern for the un or under-represented factions puts him in the most positive light. He is portrayed as a real human being dealing with injustice and bravely taking action.
On the downside. This might be a book better purchased in print form. As someone basically ignorant of these in depth historical debates, it would have been helpful to reference the extensive notes included in the print version.
The author has a perfectly good voice and delivery, so don't be put off on that account.
