Just finished my third read, and I always forget how bleak this one gets. The obvious answer is Gage Creed, the toddler who gets hit by a truck. King’s depiction of that loss is brutal, and then bringing him back is somehow worse. Church the cat comes back first, but he’s just a foul-tempered precursor. The real horror is Gage—or what’s wearing Gage—when he returns. It’s not really him, not even close. The novel suggests it’s the Wendigo or some other malevolent force puppeting his little body.
Then there’s Rachel Creed, Louis’s wife. After Gage kills her, Louis, in his total descent into madness, buries her in the sour ground too. The book ends with her returning, and that final line, 'Darling,' she says, is one of the most chilling closures in horror. It implies the cycle just continues, a perfectly hopeless ending. Timmy Baterman from a story Jud tells is another example, a soldier brought back from WWII who reveals townspeople's secrets. That story within the story is crucial—it’ Susan warning Louis knows exactly what will happen.
