Sure I read KOKO some years back. I've got no light to shed on the loose ends
or the unresolved situations you are referring to. I remember it as being a
strong novel. Very complex, with lots of brutal scenes in it. Straub's use
of language and the presence KOKO's mindset makes it a novel
that catergorizes as horror fiction. I thought of him as a half human tortured demon
that haunted the pages all the way through. A lot of the atrocities that goes down or
are hinted at also has an authentic feel that makes the nasty bits uncomfortable and
uncompromising to behold. I'd say it's a powerful novel but since it was so layered I can't
frankly remember it in detail so much.
