If I'd have realized how much interest there was in Master & Commander, I might have gone to that next. I am starting (18%) another book recommended to me by @martin321 up thread. Mainline by Deborah Teramis Christian (I understand that now she mostly goes by her middle and last name). It was written in 1996 and renewed in 2019. In Amazon there are only 17 reviews of it, Good Reads has a more respectable 154. I'm enjoying it quite a bit, but find it disconcerting that her chosen occupation is "assassin."
