All in all, pretty great.
This book is short (161 pages), and I think it's well worth the read.
I found it annoying that almost all the blurbs in the cover refer to Mark Twain and Huckleberry Finn. I suppose Ms. Rawles was inviting these kinds of comparisons herself. However, the connection is tenuous and not really fleshed out, and I think the book is all the better for it. If the narrator hadn't spelled it out that the Jim that Sadie talks about is the same Jim that travels with Huck, you wouldn't really know it. I enjoyed(?) this book more than I did Huckleberry Finn; to me it was a more compelling and interesting read.
