I have a couple of points on this story, but, honestly, they both feel so petty that I hesitated quite a while before posting.
The major one is that I didn't like the story much because it felt like a revenge-fantasy... not for the characters, but for the author. (I don't know the author from Adam, but I can only state how it appears to me.) Template characters, absurdly one-sided abuse of the main character who "just wants to be left alone," predictable plot arc of "the little guy triumphant", etc. A tale of revenge can be a gripping, emotionally engaging story, but revenge-fantasies always feel rather toxic to me... stories whose only purpose is showing how the people who picked on you in school end up cleaning toilets or dying horribly... how those people who don't share your political/social/moral outlook come to an ironic, painful end. As one of those inathletic kids in school (scrawny, not chubby) who spent all his time with his nose in a book, I confess I indulged in similar fantasies, but it's just impotent dwelling and not a particularly healthy way to engage one's mind, nor a story I'd really characterize as "entertaining."
The other point is really, really petty... I normally like Dave Thompson's readings, but in this story with a more science-based vocabulary, he fumbled the language pretty badly. ("erythrocyte" (red blood cell) is pronounced "E-reeth-row-cyte" not "air-throw-cyte") It probably only grated on me because of the six years I watched the damn things flow past on the microscope, but for future reference the merriam-webster site has pronunciation audio files for things like this.
