What have I done?

I'm Oliver Greer, and I'm on my own. My family is missing—or in hiding, as a masked man with unstoppable magic chases me through the streets.

Our own magic calls up whispers of the past, and for years we've secretly used it to help where people need it. But tonight, we touched something else.

Now a ghost walks the city, a silent spirit that brings agony to everyone in his presence.

And my enemies won't let me stop him.

To save the city and my family, I have to stay ahead of ward traps and conjured blades to discover the truth. About the ghost and the people involved in his death. About why my father was so eager to contact spirits, and how long my uncle has feared them—and now why that masked mage knows our secrets so well. How far back do the secrets go?

Who will I have to face, to undo what I've done?
