Strange, human-shaped statues have appeared in Denver Heights, statues which eerily replicate missing children. On both sides of the protective veil, fey are being turned to stone. Morgan and the Council of Fey believe that Ameil Bas-Grann is somehow behind the attacks but they are powerless to stop his mysterious rampage.

Traitors among the council have aligned with the evil magus and are working to thwart Morgan's every move. In desperation, Morgan turns to the one ally she believes can help: the Mirror Man, the single Ancient who can see everything, everywhere.

But he has gone missing.

Hoarfrost Castle, the icy prison designed to house and hold the greatest and most powerful enemies of the fey, has gone silent. Prisoners have been released to aid Bas-Grann in his takeover of both worlds.

For the first time in her life, Morgan is forced to make a decision that will impact the lives of not only the fey but the humans as well, one that could have fatal consequences if she chooses wrong.
