Luna is worried about Duncan, the new roguishly charming werewolf in her life. He's gone missing, and she's sure their enemies are behind it. She's determined to find and rescue Duncan, but her attention is split because her son is home for the holidays. Before long, her enemies are after him too. Why is all the trouble in her life spilling over onto those she cares about? To fix her problems and help her loved ones, Luna will need all the power, potions, and chocolate (especially chocolate) that she can scrounge up. But against foes who know werewolves well, even that may not be enough.
