Can’t answer for Pepperlandgirl on the second part, but I can tackle the first.
Main characters: Roberta (Bobby), writer of oat operas and owner of ageing beagle Peter who lives in a backwoods Maine town and Jim (Gard), alcoholic poet and potential nutcase with a nuclear power fixation, friend of Bobby.
Basic plot, sans spoilers: Bobby, while walking in the woods, trips over the tiniest fraction of the rim of a buried flying saucer. Without knowing what it is - just that she’s stumbled over something huge - she starts to dig it up. Weird shit ensues.
It’s a thinly-disguised moral about humanity starting up things they don’t thoroughly understand yet, like the nukes that Gard’s so antagonistic about, and that’s it’s weakness; I enjoy the characterisation, the plot’s not too bad, but I don’t enjoy being belted around the head by a moral.
It’s not exactly my favourite King book, and never will be, but it’s not King’s worst, either (Gerald’s Game wins that one, IMHO. I finished GG with a kind of “That’s all? What a letdown” feeling).
My favourites:
Novels - The Stand, Christine, The Shining, The Talisman, the DT books, It, Dead Zone.
Novellas/short stories - 1408, The Long Walk, Ballad of the Flexible Bullet (I want a fornit), All That You Love Will Be Carried Away, Paranoid: A Chant, Rita Hayworth and the Shawshank Redemption.
