Zoe is unaware that her shadow became a separate entity during her bout of amnesia. Through a spiritual revelation with the ghost of her mates, the phenomenon behind her fire is unveiled to her. She is awestruck by the nature of her gift.

While Booker is away on business, she and Rider bond on an intense level and exchange extremely intimate bites. When Rider travels south to help his twin open the new club, Zoe is left alone overnight. She ventures into the darkness and begins utilizing her fire to avenge the death of lost souls.

Zoe doesn’t like how she feels when her shadow runs amok and pleasures her mates. Even worse, she must find her alter ego before Shadow drains her soul.
