First and foremost, it must be said that Off Season is not for the feint of heart; this is a visceral, brutal, unrestrained, exceedingly realistic novel that may sicken and disgust those unprepared for such extreme horror. The cover of my copy proclaims this "The Ultimate Horror Novel." I would not go that far in my assessment, but the suggestion doesn't fall very far from the mark. Ketchum held nothing back and pulled no punches in this, his first published novel. The story is rather simple but is far from simplistic. A group of six adults (three male, three female) retreat to a remote cabin in the woods of Maine for a week of relaxation. Unbeknownst to them, a family-group of utterly primitive, sadistic quasi-humans watch, wait, and eventually attack. Among this group are a number of wild children, and it is the children that have the most significant impact on the characters as well as the reader. The battle rages for some time, and many very bad things happen as the innocent victims do everything they can think of in order to survive. I found the conclusion to be spectacular; rest assured it is not the formulaic ending we see so often in novels of this sort.
I won't attempt to describe the horrible things the depraved attackers do--imagine the worst things you can think of, then imagine how much worse the unthinkable is, then imagine children taking part in it. This really is one of the goriest, most extreme horror novels I have read, but it rises far above any charges of shock value or gore for gore's sake. It would have been a disservice to the reader had Ketchum not made the awful individuals he described behave in such a fashion; in fact, I would suggest that these characters of Ketchum's creation committed such atrocities on their own and that Ketchum the writer had no choice but to tell their story truthfully and realistically. It is this utter, unimaginable realism that really sinks its claws into you and immerses you in this nightmare landscape of Ketchum's genius. Extreme horror used gratuitously accords the author little respect in my book, but extreme horror written as honestly and dare I say respectfully as that of Off Season deserves the utmost respect that I, as an epicure in the horrible, can possibly give to an author.
