The Elementalists

Who is she? She doesn't remember. Tyde, a girl who doesn't remember her past or her real name, and only knows a part of her future from the lines of a mysterious prophecy. She makes friends, finds love, creates an identity, but all that falls into shambles when everything changes, and the biggest evil ever faced threatens her new home.
What will happen when she finds out her dark past?
And the more important question still, will they all survive?
They are the Elementalists.
