Gah I'm very disappointed in myself for not listing this as an example, under any other circumstance I push this book constantly

Hawkes in general is one of my holy grails - I've been aware of him for years but for some reason his books are obscenely hard to get hold of in the UK.

I'd definitely put film of I'm Thinking of Ending Things in this general category - I haven't read the book though because from what I could tell there wouldn't be much suspense to it if you knew where it was going. Hadn't heard of the Kupersmith one before now, but the "mysterious disappearances X years apart" subgenre usually has the feel I'm describing so I'm very intrigued!

Oh yeah, I loved Annihilation and it definitely fits into this theme!

Haven't read any Delany but this one sounds like exactly what I'm thinking of, I will definitely track this down

Been on my to-read list for years but I've never found a reasonably priced copy - from what I know it's exactly what I'm looking for though!
