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 shape comparatively: a crease on the front cover, cornerwear, and a cracked spine with slight spread. But it's a Pinnacle first printing that’s clean inside, in better shape than you often see for this one.
