The magic in this story universe is an innovative mix of innate genetic ability and physical spell work based on arcane glyphs and circles- like something straight out of a high fantasy novel. Magic has boundaries - meaning it doesn't give even the Primes, the most powerful of mages - limitless potential. I haven't enjoyed an urban fantasy book this much since the first Night Huntress book, and that series is one of my all time favorites! This series has a lot of potential and should appeal to lovers of paranormal romance as much as fans of urban fantasy, thanks to the solid writing of team Ilona Andrews and their fierce, daring characterization of Rogan and Baylor.
