Nice, quick read. I know this was written first, but I'm glad I read WAACF as a coda to Harrison Squared. Gregory's command of language here reinforces what I said about that book- it is written very deliberately to be a YA novel with all the trappings of the genre. And now I'm even more sure (because of spoilers! from this book) that there will be a Harrison Squared trilogy. 
 This novella, however, was gripping, and tightly plotted, and everything great about short horror fiction. If I was a more attentive reader I like to think I would have seen the twist involving (view spoiler)[Dr. Jan (hide spoiler)] but maybe not; maybe I realized it just when Gregory meant his readers to. I do wonder, though, having read this after its' sort-of-sequel, if Gregory pushed to call his other book "Jameson Squared" and got pushback from publishers?
