They call her Solitaire.

At just thirteen years old, she took command of the most vicious criminal syndicate in the dying undercity of Khoros Prime. No family. No past. No mercy. Just the kind of feral hunger that keeps you alive when the world above is burning.

But now the Void Covenant has come - space-born zealots whose ships blot out the suns and whose whispered prayers can crack a man's soul. While the planet's elites scramble to trade their people's freedom for their own survival, Solitaire knows the truth: when gods begin to die, someone has to be there to catch them. Because on Khoros Prime, divine beings don't stay dead unless you know exactly when and how to kill them.

Armed with industrial-grade magic that runs on blood and brass, leading an army of throwaway children who've never seen clean air, Solitaire has six days to pull off the impossible: assassinate a collaborator king, overthrow a planetary government, and stop cosmic zealots from harvesting her world's dying god.

The problem? The king she needs to kill is the same one who made her into a monster in the first place.

Some vengeance is worth dying for. Some is worth living for.

Solitaire is about to find out which kind of girl she really is.
