Casia will burn.

Earth's Hammers descend upon the lone, distant world to take back freedom she was never meant to have.

Arch Ariel is among them.

Skilled, honest, brutal—he aches to prove his worth and conquer the snarling darkness between his lungs.

But the Hammer Fall of Casia doesn't go as planned…

And when amidst death and destruction Arch stumbles upon a savage, broken child, destined for slaughter, a strange spark sets ablaze the darkness within, forcing him to save the child from his own kind…forcing him to save Elyse.

As Earth struggles to seal her claim, two times Arch will flee his fate…two times Elyse will bring him back.

A girl who quells storms with deadly rage, as tides gasp and secrets howl; a woman who sculpts worlds with icy hands, as fire, death, and love implodes from above.

And only when their bond seems spent, will Arch and Elyse discover the truth…

The future of the flame they share forever is tied to Casia's fate.
