This book features Regeane and her sworn shapeshifter mate, wolf-turned-man Maeniel, in Dark Ages Italy. In a cliffhanger opening, a runaway Saxon slave saves Regeane from death in an Alpine avalanche. When the two attempt to take refuge in a nearby monastery, they discover a mad abbott under the control of an invading demon spirit, the Bear, who leads a ragtag troop of bandits and monks turned zombies. Although they escape with Maeniel's help, the Bear follows, determined to possess a werewolf body and increase its power. Maeniel undertakes a mission from Charles (Charlemagne) to scout the geographical and political landscape ahead of the king's troops as Charles lays siege to Lombardy and its self-indulgent ruler, Desederius. In the meantime, Regeane's greedy cousin Hugo bargains with the Bear spirit and finds himself caught up in Desederius's plot to capture Maeniel. Fortunately, Regeane and the Saxon arrive in time to rescue him.
