The extreme cold of the winter will be a more deadly enemy than any soldier to the invaders. And not only these two known enemies plaque Casca's mind; he has to deal with an unknown murderer lurking close by with a mission of his own, linked to the woman Casca has vowed to protect.
And then there's the mystery of who raped, murdered and stole a valuable icon from a helpless Polish village, someone within the ranks close to Casca. The Eternal Mercenary must find the icon and the killer to fulfil a vow to a dying girl.
