The Otherworld is at war. The Academy for the Unbreakable Arts trains warriors. And Kelcie Murphy-a foster child raised in the human world-is dying to attend. A place at AUA means meeting Scathach, the legendary trainer of Celtic heroes. It means learning to fight with a sword. It means harnessing her hidden powers and-most importantly-finding out who her parents are, and why they abandoned her in Boston Harbor eight years ago. When Kelcie tests into the school, she learns that she's a Saiga, one of the most ancient beings in the Otherworld. Secretive, shunned, and possessed of imposing elemental powers, the Saiga also happen to be kin to the Otherworld's most infamous traitor. But Kelcie is a survivor, and she'll do whatever it takes to find her parents and her place in their world. Even if that means making a few enemies. Brimming with Celtic mythology, action, and danger, The Academy for the Unbreakable Arts introduces readers to a new kind of magical school and a warrior who must decide on which side of an epic battle her destiny will lie.
