I encountered the first issue of this as a Humble Bundle sampler (http://ewx.livejournal.com/626752.html) and liked it, and bought it cheap on Comixology during a sale. From a high level, the setting isn’t the most original: the world is largely divided (with a literal wall) between humans and magical halfbreeds (Arcanics). However it’s a good implementation of the cliché and the plot and characters in any any case transcend it.
The previous hot phase of the conflict between the humans and Arcanics was terminated by some kind of major and very destructive magical event, with even the known details to some extent covered up. Maika, superficially human but in fact rather more complicated than that, knows her mother had something to do with it, and wants answers from her former colleagues. As the book opens she is tactically exploiting helplessness, but she soon turns out to be exceptionally dangerous, a repeating theme being others discovering this a bit too late. This could easily have been mishandled but by in practice it stays interesting throughout; her strength, or a least her willingness to use it, does have its limits.
Maika’s principle antagonists are a powerful religious order which when not exploiting enslaved Arcanics seems to be thoroughly overrun by its own members’ private agendas, a characteristic which extends (albeit mostly in less brutal form) to many of the other protagonists, adding a realistic gloss of human nature to a fantastical world.
The volume ends with a satisfying resolution, but with open questions and loose ends lined up for further issues. I look forward to them.
