I have never seen a trailer for a book before. As Mr. Cullen writes on his own blog, this trailer gives you a "concise summary of the book and also of the killers."
I feel somewhat compelled to post this....as a teacher, as a parent, as a member of this human race.
This book was phenomenal. I know I have written about it before, but it is one of the greatest works of non-fiction I have ever read. It does a great job of dispelling so many myths and making the tragedy more real and, hopefully, somewhat unrepeatable.
