The premise is clever and deconstruction-inevitable: while Dray Prescot is off on some unspecified adventure, what is going on with his wife Delia?
The answer is a little complicated because her adventure is tied up with the Sisters of the Rose martial society and family disputes and whoops-captured-by-pirates and the intrigues of where she winds up. It isn't bad, just is not the sort of thing I would want to read in an adventure series about an outlandish space fantasy. Maybe more outlandishness appears after the point that I gave up. But the thing I kept considering is that Delia's situation and the plot outlay of capture-slavery-household-intrigue could just as easily have been set in Rome or Byzantium with practically no changes.
The primary hero of the Dray Prescot series is Dray Prescot, of course. But this book tells the story of the woman he loves, Delia, who became his wife during the series. Despite that, it is really a good read with lots of action and adventure. Delia is no wilting princess. She's a tough as leather warrior as well.
If you are a John Carter of Mars fan or enjoy the "displaced person on another world" then this series is for you. The books run in long story arcs so you can read just a few to complete a plot line or go for the whole set. Akers creates a very complex world for the hero to adventure in. Recommended
