NIGHTMARISH MACHINES HAVE DRIVEN HUMANITY INTO THE DEPTHS OF SPACE.

DENTON CASTUS is a starship mechanic caught in the destructive path of the Undriel war. The impossible machines force him and the last remaining fragments of the human race to abandon their homes in the Sol-System. Denton's journey will take him to a distant planet, where a small colony is preparing for the arrival of refugees from the war. However, this new safe haven has undiscovered threats of its own. 

ELIANA VESTON is a scout preparing the planet Kamaria for the refugees. The beauty of this new world masks the dangers that lurk within it. A pandemic named "lung-lock" is killing off colonists as the scouts struggle to find a cure. Eliana discovers that the auk'nai, a native race of technologically advanced birds, possess the last element she needs to synthesize a cure and save her people. She must convince them to help before the arrival of the refugees. If Eliana fails, humanity will become extinct. 

The hunt for a cure unleashes a new threat to humanity—the Sirens—mysterious beings with incredible powers and a deep hatred for invaders. 

It will be ADAPTATION or EXTINCTION. 

IN THE ORBIT OF SIRENS.
