Red Mage: Ascending - Tournament of Mages, #1

The servant girl has a secret..and she's hiding it in plain sight. Hana works for a well-to-do family who treats her well, but something is not quite right. The servant girl doesn't act like a servant. She speaks multiple languages including high elvish, she is an accomplished musician, and she is a skilled artist. There is also another talent, but it's a secret Hana guards closely. She can use blood magic.
She is in hiding because she knows that if she is found out, she will have to fight in the Tournament of Mages, a contest where she will be pitted against five other mages with different forms of magic. She has left everything behind, her family, her friends, and the one secret she dares not reveal.
