By John Walsh, with Susan Schindehette. This isn't the definitive account of the case, ironically, in my opinion -- that "honor" goes to the Standiford from 2010. But it's a worthy account of how a grieving family becomes an activist family.
This paperback's a great read-and-recycle copy: mild shelfwear and a cracked/cocked spine, but fairly straight and crisp otherwise.
