The Netahs fits many categories. First, it’s a YA or young adult title because the main character is 14 years old. It is a fantasy because characters can transform from humans into animals. It is a suspenseful adventure, because the hero experiences situations that are far from ordinary and he reacts sometimes bravely, heroically, or timidly. It is a romance because it includes relationships that are fraught with sexual tension. It is mythological because multiple cultures have myths about halflings created by parents who are humans and gods. It is magical realism because it is set in modern-day Colorado, with modern day people, places, technology, and expectations while also introducing a magical, secret society of transformers. In the Wikipedia definition of magical realism, it also includes political critique. Book 1 only tiptoes around that, but it arises more in book 2, so stay tuned! Something for everyone!
That said, Happy Holidays!
