“A can’t-miss entrance in another of the very best urban-fantasy series currently being published.”-Booklist (starred review)

As Chicago’s just professional wizard, Harry Dresden has faced demons, vampires, werewolves, dark sorcerers, and hosts of horrors from beyond the mortal world. But nothing at all could have prepared him for this…

Way back when, Susan Rodriguez was Harry’s Dresden’s lover-until she was attacked by his opponents, leaving her captured between humanity as well as the relentless bloodlust of the vampiric Red Court. She vanished to SOUTH USA, where she could battle both her savage present and the ones who cursed her with it. Today, she requirements Harry’s help more than ever.

For the vengeful Duchess from the Red Court has found out a secret Susan has longer kept from everyone-including Harry-and she plans to use it. To prevail, Harry may have to unleash the full fury of his untapped power-and he might have no choice but to embrace the darkness within himself.

Because this time around, he’s fighting to save his child.
