When Silas Walker is endowed with the power to heal, he soon discovers that no gift comes without a price.

A man possessed by an ancient evil is taunting the healer with photos of victims brutally murdered and marked with the crude image of an angel, and for Silas the slain are growing more familiar.

After he is given an ominous warning and an unbearable ultimatum, Silas sets out to draw his enemy away from those he loves, and discover the true purpose of his gift.

The Stalker is close on the healer's trail, bringing with him an army of demons. Silas's only hope rests in the hands of a guardian angel he doesn't even know exists.

The Guardian is doing all within his power to save the healer, but he is certain Silas is heading into a trap. Time is running out.

But there is no turning back. For even an angel can't alter a man's destiny.
