I found this book to be incredibly boring and contrived. Weir seemed to want to write an edgy female scientist so he made her promiscuous and from Saudi Arabia. Not that there's really any sex in the book, just a lot of talk about her rep and a reusable condom. And welding. It's tiresome and I had to start skimming pages in some sections just to finish. The characters are flat and stereotypical. I disliked it so much, I took myself off the library wait list for hail mary.
