Settling on a solid 3 stars. I really enjoyed the story overall, but there is a logic hole that still bothers me a bit, and thus the lower rating.

In the book, vampires have purple blood, werewolves have green blood, and humans have red blood. It's revealed that the MMC's sister is half human and has red blood. Yet somehow no one has noticed. Not even the little girl herself. Has she never scraped her knee? Blushed? How is it that NO ONE noticed this?!!!
