This is an excellent entry into the "Mars Needs Women" trope of science fiction romance. Ryn belongs to a race of men long accustomed to raiding for wives. Ziri has the misfortune of catching his eye. The set-up is such that you expect a chest-beating alpha, intent on mating. What you get instead is a sweet love story, with a hero who has been counseled by his father to be patient and kind to the woman he captures as his prize.
Lucy Varna has borrowed from various, familiar stories and cultures to create her own world for the Pruxnae and the Tersii. The science fiction elements are a loose frame around the central love story. The Pruxnae culture resembled a Viking civilization in space, with emphasis on raiding and trading practices abroad and a bucolic yet boisterous life at home. Both the Pruxnae and Vernii societies seem to lead primitive home lives (i.e. sheep farming, loom weaving and paper bookstores) where technological advances are not integrated into daily lives. The method and fear engendered of a Sweepers attack reminded me somewhat of the Reavers in the Firefly/Serenity universe, but the Sweepers had a distinctly different morphology. As bad guys, they were pretty creepy, but I couldn't get away from the sense that I was in the middle of a video game skirmish as the battle scenes between the humanoids and the Sweepers unfolded. Even the download of the Pruxnae language to Ziri seemed borrowed from "Johnny Mnemonic." For all that I recognized these bits and pieces, they were seamlessly woven into Varna's novel.
A lot goes unexplained in this book. We never find out why the Pruxnae have so few women. We never learn why technology is not more integrated. And why are the Sweepers getting more aggressive? But since this is book one, I can only hope more is to be discovered in future books.
Ryn operates on the theory that you can attract more flies with honey than vinegar. Ziri operates on the theory that she has to get away. It is a lot of fun watching Ryn practice his wiles on Ziri, all without the benefit of a common language. Hand motions and a few hot cuddles say a lot. The truth is, I really liked both these characters and was rooting for them.
This book does not end in a cliffhanger, but there are clear avenues for more stories within Varna's Pruxnae universe -- hopefully featuring some side characters we meet in this book (I'm voting for Ryn's sister's story next!).
