Yep, can confirm Brett's style of story plot is 80% back story fill-in and 20% plot advancement.
This is book three of the Demon Cycle, and Inevera's back story. Since we know Jardir and we know the story of Arlen, Brett fills in Inevera's history, and moves the plot of her world along. We have her history, her trials, her fights, her losses, and her victories. We have drama. We have death. We have victory. We have temporary defeat. We have spins and twists and loops.
Anyway, Inevera's story. She makes a vow to stop senseless deaths by men's hubris, which she fulfills. She makes a vow that women can fight just as well as men and that they will be able to, which she fulfills. She plays her husband like a fiddle, which, well, one can learn from, even if from a fictional character.
Speaking of fiddles, wow, there wasn't really much plot advancement in this book, we hear little of Rojer, not much more of Leesha, with much of the story being backstory. Well, okay, wedding and sex and the like. Apparently in this world everyone has sex with everyone else even though everyone is a hypocrite about it. Fine.
Still, I found this book interesting, and enjoyed it more than the last one. I'll keep reading, I'm enjoying the series, and GAH THAT ENDING.
