Enola Gray

There are five of them: Fire, Air, Earth, Water and Spirit.
Kenna. Alios. Demetrius. Hydra. Enola. And they are like no one you have ever met. These are the children who were born with extraordinary powers. They can manipulate the elements. As you can see, they were all special, but there was one who had powers that exceeded them all. Enola Gray- she quite literally became the heart of the group.
At the sweet age of seventeen, the group meets a new icy visitor and he cracked their foundations with a bitter tremor.
He took their heart.
