What started as a small rebellion has grown to all-out war, with the four minor islands uniting under the call for independence. But Kael Skyborn no longer trusts the mysterious leader of their rebellion, nor his disciples. Neither side seems willing to reveal the truth of the elemental prisms the Seraphim wield in battle, or the blood that keeps the islands from crashing down to the ocean below.

Bree Skyborn is the Phoenix of Weshern and the face of the rebellion. But when Kael is captured and brought to Center for execution, Bree no longer cares about the war or the call for independence. All that matters is rescuing her brother and putting a stop to the violence for once and for all.

Both sides hold secrets that could be their undoing.
