A Pitch for "The Between"

I've been working on distilling a 67K word book into a succinct pitch, and after many incarnations, this is the latest.

Any thoughts or impressions are welcome!

High school senior Lydia Hawthorne is less than grateful when Oberon has her snatched from the Mortal world and she finds out she's actually Fey. And not just any Fey, but a trueborn Fey with enough inherent magic to tip the balance between the warring Bright and Shadow courts. She discovers the long simmering conflict between Oberon and Titania is over far more than political power: the Fey are dying out and need access to the Mortal world to produce children. The court Lydia allies with will thrive; the other will slowly dwindle.

But that's their game and she doesn't want to play by their rules. Together with Clive Barrow, a Bright Court Fey with embarrassing ties to the Mortal world, Lydia fights to regain her old life. The Fey get far more than they bargain for when Lydia fuels her magic with the very Human power of love and loss, challenging Oberon, Titania, and the essential nature of Fairy itself.
