Edited by Rose G. Mandelsberg. "The most savage cases of youthful violence ever reported," illustrated on the cover with 1) terrible hairstyles, and 2) a tasteless stock photo of a claw hammer. But this paperback is, for whatever reason, rather rare and coveted.
This particular copy is in good, not great, shape: corner creases to the cover; edgewear; a crack to the spine; toned pages. But it's a Pinnacle first printing in readable shape, so grab this one while you can.
