Maika Halfwolf is from the "race" called arcanics. Arcanics are used by humans for the magic that can be extracted from them. Maika has a stump for an arm, a multi-eyed monster resides in her body and sometimes surfaces to devour others. I have a bit of a problem following the storyline, it would probably help if I reread the book. Or perhaps its intentional. Analagously, another author C.J. Cherryh has battle scenes where you're never quite sure what happened - I suspect people in battles are often unclear about everything that happened.
However, the artwork is beautiful, and the world created is lush and atmospheric. I enjoy this series.
