Eh, the furry level is really low imo, even their hybrid forms have a very animalistic face, not the weird half human half beast face that furry fans prefer (or human face+animal body). I'm not into furry but u wouldnt have to try very hard to find worse, even disney/pixar/dreamworks is much more furry than this.
Their faces nowhere annoys me as much as furry usually might, and the writing and themes carry the book for me more, anyway.
What happened to ch1-8?
