Shortly after midnight on July 17, 1918, the imprisoned family of Tsar Nicholas Romanov was awakened and led down to the basement of the Ipatiev house. There they were summarily executed. Their bodies were hidden away, the location a secret of the Soviet state. A decade later, Pekkala, once the most trusted secret agent of the Romanovs, is now Prisoner 4745-P, banished to a forest on the outskirts of humanity. But the state needs Pekkala one last time. His mission: catch the assassins who slaughtered the Romanovs, locate the royal child rumoured to be alive, and give Stalin the international coup he craves. Find the bodies, Pekkala is told, and you will find your freedom.

In a land of uneasy alliances and lethal treachery, pursuing clues that have eluded everyone, Pekkala is thrust into the past where he once reigned. There he will meet the man who betrayed him and the woman he loved and lost in the fires of rebellion - and uncover a secret so shocking that it will shake to its core the land he loves.
