Freedom Roads: Searching for the Underground Railroad

I am a student in the process of becoming a teacher, and as such I found this to be a great supplement to any text book and more informative than a fiction. This book gives more in depth information about slavery and specifically the Underground Railroad than any other book, text or otherwise, that I have ever read! I learned about the spirituals as well as the fact that there was a kind of Underground Railroadvin the 1600's-slaves fled to St. Augustine for safe haven. What a wonderful addition to any classroom!!
