Looking forward to seeing more Elli Quinn! I really like this character. I do not like Ethan or Athos, because I really despise religious/cultural fanaticism and exclusivism. But I also recognize that, since there are real-life examples which denigrate and dehumanize women, Athos' attitude towards women cuts very deep and invokes a deep-seated anger. It's really personal bias, and if there's another book focusing on Athos, I would not read it. I find myself getting quite upset. Ethan redeemed himself in my eyes when he saluted his mother, but his is a secret and likely one-off. 
 I do recognize that there are feminists in this world who wish for a world like Athos', and there are books written exactly like reverse-gendered Athos. I dislike them as well, but I admit they did not anger me as much as this particular fictional planet did. Perhaps it's time to examine these books again... 
 On to the plot: Suspenseful, fun and first time meeting Jackson's Whole denizens for me. A romping adventure ticking all the necessary ingredients. Short read though, good for a train trip.
