The other reviewers have done a great job with their commentary. Mara Leveritt's book is gripping-- I could not put it down. The West Memphis 3 case is the most blatant and appalling instance of injustice in my lifetime thus far. I have made it my mission to educate myself about this case, and if you wish to do the same, this is an excellent start!
