I listen to a lot of audiobooks, read a lot of library books and e-books, still somehow never have enough room on my bookshelves.
So this is a book that Vita Sackville-West (member of the Bloomsberry Group, sometimes lover of Virginia Woolf) wrote half way through the second world war. I had thought going in it had a similar premise to Farthing by Jo Walton, but no, in this book the Nazis conquered the UK and Ireland, and the US having won the Pacific War made peace with the Third Reich. The story follows a group of characters in a hotel on the rim of the Grand Canyon, about a year after these events. The two main characters are both English expats living in the hotel, and there are US air force officers, a bunch of college kids, and a handful of other European refugees, plus the hotel staff. Some of them will be turn out to be Nazi Fifth Column, some will be up to no good in other ways, and war draws closer by the day.
Sounds exciting, right? Yeah, no. It wasn't. This is a short book, and it took my ten days to read it (granted I was busy for much of it, but still!). The two main point of view characters spend massive amounts of page time hanging out and chatting, mostly about their opinions of the other characters, especially one of the college girls. Who does not and never will have anything whatsoever to do with the plot. At all. They also talk about their experiences during the war and current events, but seriously massive page time on stuff that isn't interesting and won't matter to the story.
The style is very dialogue heavy. Everyone gets long monologues either aloud or internal about their feelings about each situation, and absolutely none of it is anything a human being would ever say, though maybe it works for thoughts some of the time. There is also a good deal of racism directed at the black musician characters, including the N-word a couple times, and an ambivalent relationship with the Hopi characters.
However, for all that? I still found it absolutely fascinating. There are some SF elements in the uses of technology (there are supersonic heavy bombers in 1942, and undisclosed WMD that was used to defeat England, and underutilised technology that can draw electricity from the air ala Tesla), and then the last third has a strong fantasy element that I won't spoil but which was used to great effect. I also really liked a lot of the responses to trauma that the female PoV character was working through, and a lot of her interactions. A lot of the writing especially the descriptions of place and emotion were gorgeous.
I think if you're interested in the evolution of alternate histories, especially of WWII, or of Sackville-West. If you're going to be more interested in everything that's happening off page, you might find it incredibly frustrating.
