I'm not sure what it means, but on pre-orders alone, "Facing Violence" is currently ranked #7858 on Amazon out of more than eight million books. According to the secret author page, it hit a high rank of #5748 Wednesday.
Those are numbers. My assessment, as the author, is that "Meditations on Violence" was more personal and visceral than "Facing Violence" but that "Facing Violence" is infinitely more practical and useful. In the end, as always, the readers will decide.
