The Darkness is coming. 
When it strikes, Volka, Carl, 6T9, and Sundancer will have to join forces with an unlikely ally to learn the key to defeating it. An ally who is cold, cunning, and despises all of them - Alexis, Captain Darmadi's wife.
If Volka and Carl can manage not to kill her, 6T9 can refrain from sleeping with her, and Sundancer can keep them all from being blown up, humanity may have some hope.
Strap in! It's bound to be a bumpy ride.
The Defiant takes place in the Archangel Project universe.
