I *did* enjoy this book - the style is sensual, the werewolves' world hypnotic and imaginative, and the verismultitude of the ancient world she describes is compelling.
However, Borchardt has certain issues with keeping her characters' motivations and personalities consistent, and sometimes she over-emphasises their reactions (people gape, scream, and gasp when merely being a little suprised would do) and, compared to the richness and imaginativeness of the descriptions and situations in the book, the people inhabiting them occasionally seem rather contrived.
For instance, Lucilla and Hadrian lurch haltingly between displaying friendship and enmity to the heroine, without much internal consistency. Lucilla, in the course of one conversation, is exulting one minute and completely miserable the next, while Regeane's evil uncle is never really characterised at all - he's just this cypher for evil. It all gives the peculiar impression that the characters are all suffering from some form of manic depression. That said, there is a lot to appreciate here too - Maeniel is a likeable figure, as is Regeane (though in truth after her engagement her cringing relations with her uncle seem rather unbelievable).
I would read another in this series, but to be honest Borchardt could do with much more fastidious editing and a firmer grasp of her characters.
