Healing wars

Nya is an orphan struggling for survival in a city crippled by war. She is also a Taker-with her touch, she can heal injuries, pulling pain from another person into her own body. But unlike her sister, Tali, and the other Takers who become Healers' League apprentices, Nya's skill is flawed: She can't push that pain into pynvium, the enchanted metal used to store it. All she can do is shift it into another person, a dangerous skill that she must keep...

With the rebellion in full swing, fifteen year-old Nya's loyalties are put to the ultimate test, and she is forced to choose between leading an army against the Duke or abandoning her people to save her sister.
