The Sorcerer's Daughter--what it's about

I've reached the end of Part I of The Sorcerer's Daughter so I'm going to take a few days off from it before starting on Part II.

It's the story of a girl named Drew. Part I begins when she's nine years old and her father comes to claim her from her mother and she learns of her terrible birthright--her father is the Sorcerer, who defends humanity from threats from other worlds. She is to be his eventual replacement, and he comes to claim her to begin her training.

Part I is about her training, and her continuing journey to adulthood with a crazy, mixed-up upbringing--her mother raised her according to her father's explicit instruction but also showed her love and empathy. Her father, on the other hand, is cold and aloof and the ultimate pragmatist. He'd have no problems sacrificing part of humanity to save the rest, and, while he defends humanity as a whole, he rarely forms attachments to particular humans. He also does not defend humanity from itself--he can step in and stop a lot of problems before they erupt into conflagrations but refuses to do so. He also rarely responds to pleas for help from the few individuals who even know he exists--he considers that a waste of time. However, he is enormously powerful, and dedicated to his duty, which supersedes all of his other considerations. Even his duties and obligations to his daughter.

Drew has to learn how to think as he does, how to be aloof and cold-blooded when circumstances warrant, but also how to identify and empathize with humanity so she'll be willing to expend the effort to save it, even sacrificing herself if necessary.

Part I ends with Drew allowing something to happen that she knows will have terrible consequences, but also achieving a major milestone in her learning how to become a Sorcerer herself. Part II will be about a more grownup Drew--she's around fourteen at the end of Part I and around seventeen at the beginning of Part II--still learning, but a lot further along in her development. She's learned a lot in the three years, but the biggest lesson of all will be revealed in this part.

Part II is going to be structured a bit differently from Part I, which is why I decided to divide it up like this. Part I skips over a couple of years in the narrative a few times, just sketching in the important details. Part II will be a bit more of a continuous narrative, a bit more of a traditional story, as Drew grows into her role as a Sorcerer and her father's eventual successor.

I'm going to maintain a tone throughout that's quite dark, while not depressing--mysterious, but not enigmatic. I do intend it to be a Young Adult story, so I have a bit of a tightrope to walk with some aspects, but that's part of the fun, I think. I consider it a Dark Fantasy--not horror, per se, but with some horrific elements.

Anyway, that's what it's about. What do you think? Sound interesting?
