Lou and Reid are reunited. But after a narrow escape from Morgane’s dagger, they are pursued on all sides by coven, kingdom, and church. Together, they were sure they would be able to conquer anything. Now, they need allies to survive. Strong ones. And only one person can hide them: La Voisin—Queen of the Dames Rouges and sworn enemy of Lou’s coven. But when Lou turns to a darker side of magic that she believes is necessary to protect her husband and friends, it may cost Reid the one thing he can’t bear to lose. Bound to her always, his vows were clear: where Lou goes, he will go; and where she stays, he will stay. Until death do they part.
