ance, and awesome action"* of Nalini Singh's New York Times bestselling series continues as two Arrows are caught in a chilling conspiracy that spans all three races...

Awakening in a darkened cell, their psychic abilities blocked, Aden and Zaira break free from their mysterious prison, only to find themselves in an inhospitable landscape far from civilization. To survive they must make it to the hidden home of a predatory changeling pack that doesn't welcome outsiders.

And they must survive. A shadowy enemy has targeted the Arrow squad, and Aden will cross any line to give his people hope for a new future. Zaira has no such hope. Too damaged to return from the abyss, her driving goal is to protect Aden, the only person who always comes back for her no matter what.

But Aden's passionate determination may not be enough. The emotionless chill of the Silence Protocol existed for a reason: for the violent, and the insane, and the irreparably broken...like Zaira.
