Elevation (2018) by Stephen King: A novella set in Castle Rock -- much like King's low-key 2017 collaboration with Richard Chizmar, Gwendy's Button Box -- Elevation is a story about a kinder, gentler Castle Rock, though not one without its flaws and magical weirdnesses.
In this case, our middle-aged protagonist discovers that he's losing weight. Not mass, weight. Steadily and perhaps even increasingly rapidly, he's gone from 240 pounds to 210 pounds without looking as if he's lost any weight. And anything he carries or wears loses ALL its weight. A recognizable medical condition, this is not.
However, unlike the vaguely similar Thinner, Elevation is not a horror story. It's a quieter fable of smaller kindnesses and redemption spurred by that weight loss. I'd compare it to Ray Bradbury if King were a poetic writer like Bradbury. In this case, though, King's own dedication -- to genre great Richard Matheson -- seems apt, at least for Matheson in his quieter moments.
Rod Serling's Twilight Zone would also be an apt comparison, with one Changed Premise illuminating the good parts of the human condition as well as the bad. Think "A Passage for Trumpet" or "In Praise of Pip," two gentle, sad TZ episodes starring Jack Klugman. And a middle-aged Klugman would actually make a good fit for our protagonist!
It's a slight work but an enjoyable one, and it's not going to take you long to read. I'd almost swear that an embattled lesbian couple in Elevation may have appeared in the first draft of King and his son's Sleeping Beauties before being cut. They're embattled because small-town Maine isn't ready to patronize the restaurant of two openly gay women. Or is it? Recommended.
Gwendy's Button Box (2017) by Stephen King and Richard Chizmar: In 1974, twelve-year-old Castle Rock native Gwendy Peterson meets a man in black sitting on a park bench. He's peculiarly convincing but no pervert. No, he wants her to take on stewardship of a peculiar small wooden box covered with buttons. She's the best person for the job. And as compensation, the box dispenses rare silver dollars on occasion and one exquisite chocolate once a day.
So begins this peculiar, affecting coming-of-age novella/short novel (it's really an abbreviated kunstlerroman). King handed it in unfinished form to writer-editor-publisher Richard Chizmar, who came up with ways to finish the narrative. The two work seamlessly together. The prose is a bit leaner, perhaps, than the King norm, but I'd be hard-pressed to figure out who wrote what.
The gem here is the character of Gwendy, who is perfectly believeable in the midst of increasing weirdness centered on that box and those buttons. As to who the Man in Black is -- well, I'll leave that to you. He sure does like the word 'palaver.'
The horror in Gwendy's Button Box is mostly quiet and psychological, though King and Chizmar do throw in one gross-out scene, a brief one. In all, a rewarding, short read. Recommended.
