FROM MILLION-SELLING AUTHOR JACK SLATER

What's a life worth?

Gideon Ryker is learning that the fanatical cult known as the Brotherhood only worship power. He has their tyrannical messiah Father Gabriel chained in a cellar -- but a brutal new leader has seized power in his place. And while Miranda may want Gabriel gone, many in New Eden still worship him.

That makes him dangerous leverage... and Gideon isn't the only one who knows it.

With the Faithless reeling and his sister's fragile freedom at stake, time is running out. Hunted by a new tyrant and courted by spies and criminals alike, every move on the board risks disaster. But this isn't a game. Some moves can't be taken back.

And the price of failure isn't death. It's extinction.
