Eighteen years before the events of Run to Earth, the Elementals lived in harmony together in the City of Marwa. But the youngest of the Elementals, Alex Adams, has a secret. One he's had to keep from his own brother, Christopher, because he knows Chris would never tolerate it.

But with Alex soon coming into his full powers, he knows time's running out to tell Chris the truth before it's revealed at his coming-of-age ceremony. With the brotherhood of the Elementals already under strain, will Alex's secret cost them their unity?
