I usually don't reread books frequently, and when I do, it's with enough time between readings, years normally but I have read twice each book of this series in something more than a month, and all I can say is that i like it, has an entertaining story, well spun and with good rhythm, a protagonist with whom I empathize and I want to know more, witty situations, something spicy and fun.
I don't consider myself a fantasy or hard science fiction reader, I prefer stories that begin more or less in the normal world and little by little, you are presented a more complex and fantastic world, and this series works well this way, if I would had to place it in some gender or category (which I don't care at all) it would be urban fantasy.
Now for the author, please keep writing, otherwise Cassandra will pay you a visit :-), on the other hand, be careful with the breadth of the world and the plots that you are creating, until now everything has been very well fitted, but there may come a point that be too broad, please be careful and keep it up.
English is not my language, so I apologize for mistakes
