Highly recommend
I highly recommend "The Long Way to a Small, Angry Planet" by Becky Chambers. Best book I have read in a long, long time. Was very surprised when I learned that it was her first book.
If you get the chance, read it. It doesn't matter what type of SF you like, it has a little bit of everything, you will not regret it.
Oh, and "Children of Time" was indeed authored by Adrian Tchaikovsky, not Andrew. Not a bad book but.... to me a little too much of a rehash of previous books I had read.
