I received a free copy of this book from Story Cartel in exchange for an honest review.
While there are a few interesting tips in this book on writing non-fiction books for Kindles, there’s really not a lot of things we haven’t seen in a dozen other books. To separate a 72-hour book from a “quick and dirty” one is patently ludicrous. There’s no difference, and there’s not nearly enough emphasis on putting out a quality, non-plagiarized product. The author does at least stress a need for research, but I think a tad more than 2-12 hours might be required for ANY subject you might want to publish an e-book on.
