Earth

Sage Johnson lives in Hawaii with her best friend Kiera Watts, until one day she and Kiera find out that they are different. They are taken to the continental U.S, to a special place where elemental children (Earth, Fire, Water, Air) like them can train to fight the darkness. Sage, Kiera, and the two other girls find out they are different, even from the rest of the elemental children. They are Key Keepers. Unfortunately, they lost the keys a long time ago and must learn to work together to retrieve Sage's key at the very place where she found it the first time. ********** Note: The percy Jackson books may have influenced this story a little, but most things (like the characters) are mine. I did not use any direct references, though.
