This is one of those books either I lost it, or I sold it (or I gave it away), either way, I will probably never see another copy again, which is a damn shame, because it was an utterly unique comic book, published just when comic books were starting to get treated seriously as art (it was published over 30 years ago, and has probably been out of print for at least twenty years -- I wonder how it would be looked at today, if it had been published in 2019, rather than 1989?)
I recently stumbled across a reference to this book (just as I stumbled across a reference to the OTHER book I am giving a five-star rating to today -- the now-obscure, long-forgotten "Rumours of a Hurricane" by Tim Lott) and was surprised I hadn't already rated/reviewed "Gregory" on Goodreads (in fact, very few people on Goodreads HAVE rated and/or reviewed the novel...so I feel an obligation to throw my 2-cents worth in) and was immediately overcome with nostalgia. Yeah, it's a comic book about a non-verbal kid with a big noggin, who lives in a "One Flew Over the Cuckoo's Nest"-type asylum with his only friend being a rat named Hermin the Vermin, but Marc Hempel packed more humour, pathos, and general humanity into this slim volume than most authors work up for a 500-page "literary" novel. "Gregory" made me laugh, made me sad, left me feeling uneasy...but mostly, made a lifelong impression, because it touched my heart. (Seriously.)
("Rumours of a Hurricane" was pretty good too, because, like very few books I had read before, and very few books I have read since, it presented a family (British; 1980s) that I came to care about as if they were real people going through a huge societal change, rather than just stock characters in a "big" novel -- the type of "big" novel American post-modern literature has been attempting to deliver for the last thirty years, but generally failing at -- leave it to a Brit (and not even Martin Amis!) to write what I personally consider to be one of the key novels of the 1980s!)
