Sure. I'm a fan of King btw, it's fine to admit he has a slightly weird fixation on boobs and fat people and still enjoy his work/think he's a decent person. I excluded several instances that seemed more natural or necessary than these, although I have only read Night Shift out of the two specific works you requested.

Night Shift:

"My sister was a girl with pigtails, still without breasts." (pre-teen girl)

"There is a rolling IV tray with two bottles hung from it, like a Salvador Dali dream of tits."

Everything's Eventual:

"(Roland believed this one might be a woman, with the dangling vestiges of breasts beanth the vest it wore)"

"The one in the red vest was female. Her bare breasts swinging beneath the dirty red vest were the last things he saw..."

"Or maybe she's blowing GM cowboys in Austin or Wendover - bending forward until her breasts press flat on her thighs beneath a calendar showing tulips in Holland; gripping set after set of flabby buttocks in her hands and thinking about what to watch on TV that night, when her shift is done."

"I was aware of her breasts pushing against me, and the wet, warm clamminess over them."

"I could feel Diane's breasts brush against my back as she gasped for breath."

"She wore the medal until breasts grew around it like ordinary miracles."

"(the head housekeeper, she of the formidable gunshell tits and set, red-painted mouth)"

"I would meet a cute chick with nifty little tits"

"She sounded like the kind of woman who needs a smack every second week or so to keep her tits up."

I really enjoyed The Terror by Dan Simmons, so you could give that a try if the premise sounds interesting to you. It definitely nails the slow burn suspense/horror elements you mentioned, and I personally loved the survival horror aspects of the novel. Many of the characters were interesting to me but I wouldn't describe character development as a big feature.

Otherwise, Lock Every Door was a fun YAish listen, and more character driven.

I'm also a King fan – if you haven't read The Outsider or The Institute yet, you might like them. The Outsider has more of a true crime bent and The Institute is tonally similar to Doctor Sleep.
