Imagine - The Elementals, #1

A fierce wind and a blast of green light during a strange storm causes everything to change for Katharine Bowers and Becky Thatcher. The girls wake up in Oren, an entirely different realm than their earthly city. They meet Enalie, a fading magical presence who sets an incredible destiny before them. then simply disappears. Left alone to fend off creatures that hunt them in the night, they must relay a magical heritage that doesn't make sense, and--if possible--save a world that they know nothing about.
