Them, the Others, and Emma

Emma has always been quiet. She doesn't contribute to discussions in class. She keeps verbal communication to a minimum. It's probably just as well, too: there's a smaller chance she'll accidentally blurt out that she's a telekinetic.
Emma thinks she'll glide through life with her little gift, not doing much. But she's thrown off course - literally - when her school bus crashes. She discovers she's not alone, and she's pulled into a battle that's been going on for years.
Caught between two secret feuding towns, hidden in the bush, Emma is forced to become either the hero to unite them, or the monster that destroys them all.
The worst part is, she has no control over which one she'll turn out to be.
