Books

Asimov is really good. If you are hesitate you can read I, Robot. Which is a collection of short stories to give you an idea of his writing style.

His books are pretty quick reads and high quality.

I really enjoyed the novel Children of Time by Adrian Tchaikovsky. As someone who also thoroughly enjoyed the Expanse this definitely gave me some similar vibes even though the stories aren't similar at all.

Iain M Banks's Culture novels. User name is relevant.

The Expeditionary Force novels are solid and even better if you like audio books. We Are Legion (We Are Bob) and the follow up books by Dennis E Taylor, if you like project Hail Mary these have a similar tone. Hyperion is a classic, but is fantastic!

I'm enjoying To Sleep in a Sea of Stars by Paolini. Though it is a bit long, it has lots of character development and I thought had a similar vibe to the Expanse. Also available as an audiobook which is excellent.

On the lighter side there is The Long Way to a Small, Angry Planet by Chambers (1st of a series) which I think are all excellent Adult/YA Space Opera and more in line with the Weir books.

If you haven't read the Bobiverse series yet, you're in for a treat. The first book is called We are Legion (We are Bob). The books are easy to read, and somewhat light-hearted, while tackling serious philosophical questions. The first 3 books are right at the top of my all-time favorite sci-fi.

I read Solaris recently and was genuinely blown away. Anything from Ursala le Guin is also an excellent choice although I would suggest "the Dispossessed".

I would usually recommend some Alastair Reynolds to anybody into science fiction. I always suggest starting with House of Suns because it's a stand-alone novel that is really good and will give you a pretty good idea of what to expect from his writing. But his Revelation Space series is where the bulk of his writing is. However, I wouldn't call his work fast paced. So you might not get into it.

I have recently been reading the Murderbot Diaries. They are extremely easy and enjoyable reads. Could definitely give those a try.

If you enjoyed Recursion, you would probably like another book by Blake Crouch, Dark Matter.

Infinity Gate by M. R. Carey while definitely not his best work (see The Book of Koli trilogy which is outstanding but more dystopian), is a fun multiversal sci-fi romp.
