That's what I read (mostly)
Thrillers aren’t generally my thing. The characters tend to be two dimensional and hard to get invested in, particularly female characters. That holds true here. There’s no sense that they’re real people; they’re just vehicles to carry the plot forward. The tech and the weapons are the stars here.
This is not a series that follows the same characters through each book. But you learn more about this world as each book progresses, so I would still recommend starting at the beginning if you haven’t read any. (Plus I think the first book is the best.)
I will read anything Martha Wells writes. The Murderbot Diaries and The Books of the Raksura are both excellent. This series, while very good, is a level below those. I wouldn’t start here if you’re new to Martha Wells. Or to Ile-Rien.
