I found this to be an extraordinarily well told account of the days of slavery and of the legendary John Brown through the youthful eyes of "Onion". The story is so engrossing that I was oblivious to the 400+ length of the book. It certainly doesn't seem that long. The author doesn't hold back any punches and includes liberal use of language using racial terms we thankfully find offensive in today's world. This of course builds up the feeling of authenticity throughout the novel.
This is an exciting read and one that should be great for high schoolers studying history as well as for adults who enjoy historical fiction, especially that dealing with times building up to the civil war. The depiction of the raid on Harper's Ferry is truly vivid. I can't recommend this book enough.
