Rachel Hartman

Seraphina, half-dragon and half-human, searches for others like her who can make the difference in the war between dragons and humans in the kingdom of Goredd.

In the medieval kingdom of Goredd, women are expected to be ladies, men are their protectors, and dragons get to be whomever they want. Tess, stubbornly, is a troublemaker. As her family plans to send her to a nunnery, Tess cuts her hair, pulls on her boots, and sets out on a journey.
