Children of Time and its sequels are top notch, especially if you love animals and commentary on societal roles. It’s in my top Sci-Fi.
If you enjoyed Children of Time, definitely check out “A Memory Called Empire” by Arkady Martine. It’s a Sci-Fi political mystery with lots of fun word play. Aside from some really cool tech, the book really tackles what it means to be “Other” and how colonialism effects one’s idea of self. Some really cool ideas in this book. Easily my top Sci-Fi read this year.
Both great series. Revelation Space was my intro into hard sci-fi. What a freaking ride that story is.
