The Complete Six Book Series of Spaceships and Magic. Spaceships and Magic, #8

Born of human parents on an Earth occupied by alien invaders, Juri Turner has been changing into something other than human since the age of three. When she is fifteen, she is not thrilled to learn exactly what it is that she is becoming, that due to an ancient enchantment, she has been saddled with the job of saving two worlds. Things don't always go as planned and sometimes circumstances introduce conflicts that are hard to overcome.
Nevertheless, she perseveres through betrayals, an unwanted betrothal, nasty demons, and equally as nasty aliens, because she has no choice. But most of all, she perseveres because she has no desire to see either world destroyed. Will she be able to complete her preordained tasks?These six books follow Juri as she matures and goes from being an unloved, weird human teenager on Earth to a magical dragon on the world of Mur in another dimension, and then on to other realms and out into the galaxy to other planets.
