Can you imagine being able to heal someone's injury or sickness by touching them? Would you want to do it if it meant that their hurt became yours? What if you knew that you could you then move it from you into an enchanted metal? I think this sounds like an interesting power for sure. Nya, however, may wish she didn't have to think about that problem. She can draw the pain and injury out of people, but she can't sense the metal to move it out of her. She can only pass it on (shift it) to another person.
Unfortunately for Nya, this is a rare gift, and not one that she wants people to know she has because other people may want to use her as a weapon. Then, when some of the Takers (healers who can shift the pain to the pynvium, or enchanted metal), including Nya's sister Tali, start to go missing, Nya must decide how far she is willing to go to save them. Will she use her power to make money to purchase pynvium to help the Takers?
The Shifter by Janice Hardy (Lexile: 630; Interest Level: Grades 5-9) is an interesting fantasy in which the good power is also the bad, in which things aren't always what they seem, and in which healing power is the great commodity that everyone wants. Those looking for a little different of a story will certainly want this one on their list. This is the first book in The Healing Wars series. (370 p.)
One of the reasons I became an elementary school librarian is so I can read children's books.
