Stones by William Bell

So considering I've already read half of the other choices, I am picking Stones as my book of choice from the other novels. I would mostly likely like to read this one because it has a large part doing with the underground railway and slavery, etc. I used to be really into that, and haven't been lately. May be neat to see if I still found that all fascinating. Although this book sounds more "magical" and unrealistic than other non-fiction books I have read, I a sure I'd like it on some level. Even just as something to read when I am bored!
