War of the Compass Rose

Xiaye Vernet is a sixteen year-old with an amazing advantage.
She's hybrid. She's got wings. But she's not half bird.
She's half Delfüngaye. Her mother was from a whole different universe. And now she has to take over her mother's position as Queen. Which means she has to protect the guide book called a Compass Rose to all four universes from aliens called Agents that are threatening to destroy the universe.
And then there's Avenlae. He's a queen's guard, and has trained her and been with her since she went to the other universe. But there's also Darinrain, who is the Prince of the neighboring tribe. So, her problems go as so:
1. She's queen of a civilization she's never heard of
2. She has to protect something she know almost nothing about
3. She's being attacked 24/7
4. She's in another universe for crying out loud.
5. Avenlae
6. Darinrain
