A Push

Two girls, two paths. When they were younger, Serafina and Raven were friends. A girl who broke the law by being born, and the princess who had to uphold that law. But they don't fight each other, and they become friends. But everything changes when Serafina leaves, and they're both plunged down different paths. Raven, a reluctant princess, forced to hide her powers, and Serafina, a ember-wielder, who controls fire, an illegal element. After many years, they finally meet up again. But what happens when they meet again and find they're on opposite sides...? Also, let me know if you'd like a whole series!
Please note: This story is dark, and if I create a series it won't have the same ending.
