Powerful magic makes you useful-until you're considered too dangerous to live.

I always knew there was more to my enigmatic client, Mephisto. I just didn't expect his secrets to be tied so tightly to my raven mark-or my survival.

He's unpredictable and a wildcard. With half the supernatural world watching me like prey, I need every ally I can get. Even the ones I don't fully trust.

Things go from bad to worse when the most powerful vampire in the city hires me for a job. On paper, it's simple: broker the acquisition of a weapon capable of killing vampires faster than a stake through the heart. No betrayals. No collateral damage.

I fail spectacularly-and the fallout looks like betrayal.

Now I have seventy-two hours to fix my mistake. There will be no second chances. If I fail, he'll take my life as payment.

The clock is ticking, and Mephisto is at the center of a game I'm only beginning to understand. One that's dragging me deeper into a world where trust is a liability and power is the currency.

Survival has never been easy.

This time, it may not be enough.
