Recently finished the 2018 sci-fi novel The Gone World, by Tom Sweterlitsch. Very mixed fellings on it, on the whole.

Without spoilers, it has some major plot elements regarding time travel that really don't sit right with me on a moral basis, and I thought the ending was weaker than the rest of the book.

But it's refreshing in the sense that it reads like 1970s science fiction: the big looming threat is totally alien, the mechanics of the universe are consistent and well-thought-out, and the storyline isn't composed thinly veiled $CurrentYear themes.

So, take that mixed bag for whatever it's worth.
