When shadows fill the night, it's hard to tell friend from foe. With young to raise and her Pack under attack, Sylvan, Alpha of the wolf Weres, takes on her greatest challenge when she determines to uncover the faceless enemies know as the Shadow Lords. While her mate Drake struggles to find the link between the deadly Were fever virus and the mutation she carries, Sylvan calls upon her allies among the Vampires and Fae to defeat the secret pact of humans and Praeterns bent on destroying her and those she is bound to safeguard. Liege Jody Gates, Sylvan's ally and heir to a powerful Vampire Clan, must choose between her promise to Sylvan and her duty to Clan when she aligns her forces against the deposed Vampire Regent Francesca. If the battle to come is lost, all the Praetern species will be sentenced to exile in the shadows.
