I just finished The Shifter by Janice Hardy, the first book in The Healing Wars series #1. In the community where Nya lives, the conquering Duke has made life very difficult for Geveg residents, especially orphans like Nya and her sister Tali.

Nya is relieved that Tali has been accepted into the Healers' League, but Nya still has to struggle to survive. Even though she shares her sister's healing gift, Nya is different. She is not able to take pain and pour it into pynvium, but has a dangerous ability that she must keep hidden: she is able to shift pain from one person to another.

As Nya learns more about what is going on at the League, she finds that her abilities are even more complicated than she realized. She is faced with some tough choices that challenge ideas about right and wrong, forcing her to explore just how far she will push herself to save those she cares about.
