The premise of the book is very honorable and inspirational, as it examines the workings of the Underground Railroad, one of the great resistance movements in world history. Unfortunately, the quality of the book is very uneven, and the writing is not always precise, and is often not at all concise. The prose often sounds as if it were taken out of a mediocre novel. An example: "...the United States moved ever closer to another kind of darkness, one in which men from the North and the South with Bibles in their pockets would kill each other over an idea already coughing and wheezing on its death bed." If one of my eleventh grade history students turned in a paper written in that fashion, I would ask him or her to rewrite it. More significantly is the superficiality of the study. While reading the book, it often felt like I was looking at someone's family photo album, where each photo was related to each other, but there were few common threads or themes. The author presents a series of stories (i.e.,the individual photographs in the "album"), and while a couple contain narratives that deeply explore the story of a man and woman running from slavery, many seem like just a collection of names and small towns in the rural north. In the section of the book that examines interracial couples, the author has a chapter that is just a timeline of the "highlights" of the history of interracial relationships in the United States. I'm not sure why the author chose to provide this type of timeline for this one part of the African-American history, and not, for instance, the history of lynching. At times she goes off on real tangents (why all the details about the developments of military technology during the Civil War? What on earth does that have to do with the Underground Railroad?). I did take away a few interesting stories that I will use to illustrate some of my classes, and I was very interested to read that one of the descendants of a runaway named William Still was a man named Arthur (Art) Still, who played defensive end for a couple of seasons with the Buffalo Bills. In the end the book did confirm a couple of important truths about American slavery: its application was very, very idiosyncratic and uneven (the author had an interesting phrase for this, as she called American slavery a "shadow land"), and American slaves were constantly looking for ways to undermine the institution. It is a short book (and it could be shorter, considering how wordy the writing is and how many irrelevant facts are included), but if one wants to tackle a quality book about the Underground Railroad, I would recommend Eric Foner's "Gateway to Freedom."
