Force of Fire (the Fire Queen #1)

Pinki hails from a long line of rakkhosh resisters, demons who have spent years building interspecies relationships, working together to achieve their goal of overthrowing the snakey oppressors and taking back their rights. But she has more important things to worry about, like maintaining her status as fiercest rakkhosh in her class and looking after her little cousins. There is also the teeny tiny detail of not yet being able to control her fire breathing and accidentally burning up school property.

Then Sesha, the charming son of the Serpentine Governor, calls on Pinki for help in defeating the resistance, promising to give her what she most desires in return -- the ability to control her fire. First she'll have to protect the Moon Maiden, pretend to be a human (ick), and survive a family reunion. But it's all worth it for the control of her powers . . . right?
