Another fantastic short story is The Sleepover. Most of humanity is in hibernation and is being haunted by ethereal lovecraftian entities.

Turquoise Days was the first short story I read by him, and I think it could make a fun movie.

Loved those! Super weird and interesting.

I still think about Diamond Dogs every so often. Kind of gave me the same vibes as the movie, The Cube

Yeah, the prologue and the interspersed bits with Bowerbird (I think that was her name) and the future people was a little weird, but not too jarring. They come into play toward the end of the book with the gift box nanotech thing, so I guess it was necessary to frame them in. It took me a while to figure out how they sent it from the future, but it was time dilation the whole time so no time travel.

House of Suns is my absolute favorite of Reynolds' work. It's the least "hard" sci-fi of the bunch but still follows the rules and basically takes all the ships and tech from his other works and cranks them up to 11. Such a fun read.

"Terminal World" is another fun standalone book from him if you come across it. If you feel up for a trilogy, the "Revenger" series is a fun space pirate adventure I quite enjoyed.

Yes, there is an import feature that works really well now, very simple to add books and connected to a few catalogues

Totally understandable how that can cause friction but know that you can add missing books manually.
