i read his first novel and enjoyed it but to me he felt like a one hit wonder. it's a unique style but i imagined he would just repeat it. it would be good if he did something different not just in setting but style.
OK, book was a page turner, but "meh" in my opinion.
The one thing I was not too happy about: Cultural appropriation
Weir's hero in the book is called Jazz, and she supposedly is a 20something woman of Saudi origin with a devout muslim father. Now, just writing that, but keeping the tone of the book similar to that of "The Martian" (a nerdy bloke with some quick, sarcastic, humour) means to me that he simply (in my opinion) did not pull that off.
Granted, I can not give an example of the correct style I expect from a 20something Saudi woman who has grown up on the moon myself, but IMO neither can Weir. So why bother with it, apart from the other concerns?
