Anonymous wrote:IMO, Stephen King is a better short story writer than a novelist, especially once he became "Stephen King Inc." and could basically do whatever he wanted, including ruining The Gunslinger by rewriting it and publishing a truly bloated extended edition of The Stand. (FWIW, I read both The Tommyknockers and Needful Things, so I have earned this opinion even if you disagree.)
The best place to start with his work is early, with the short story collections Night Shift and Skeleton Crew. His best novels are Salems Lot, The Shining, and Pet Sematary.
His late work is very hit or miss for me, but if you want one that is entertaining and not focused on the supernatural, I actually rather liked Billy Summers (2021), which is a straight action story that only alludes to supernatural elements. Have not read the JFK one, which many rave about, but to me reeks of baby boomer fan service. YMMV.
Addendum: The Outsider (2018) was also a fun read, but it defintely has some NC-17 elements so may not be the best choice here.
