Joanna just wants to spend the holiday curled up with her coven of handsome professors, but family obligations wait for no one. Instead of wintery cuddles, she's up to her neck in the Pike brothers and their wives, a cast of political figures invited to their dinner parties and, worst of all, Callum's father, Duncan. Duncan Pike is a nasty piece of work—not only did he place a young Callum in the heart of an ugly war, he disapproves of Isaac and Aiden.

Duncan claims a new war is coming, and it looks like he might be right. As if that weren't enough, the infamous warrior Sabine York is showing a marked interest in Callum—is she after revenge? Or does she want to add Callum to her coven of soldiers?

When trouble strikes and Callum is separated from the rest of the coven, Joanna, Isaac, and Aiden must travel from the library to the capitol to Vermenia, desperate for their reunion. And, on his own for the first time in years, Callum must tread carefully back into the waters of war he's spent decades avoiding.

Can they fight through the people and the miles standing between them and return safely together again?

Contains mature themes.
