Erin is the werewolf Queen of Athol Castle. She has no memories of the events of a few months ago, where she believed herself to be a psychologist, and met the enigmatic and charming Conner... Filtiarn has taken over Conner's body once more, and is relishing being in control. Cruel and sensual, he decides to work on a plan...to take over humanity. He begins a war...of werewolves against humans. But unknown to him, Conner is fighting against him within his own body, to set things right, and to bring Erin back from her own darkness. He tries to undo a great mistake from long ago, using Erin's famed sword, Sioctine, as remnants of his own memory come back to him, opening up the present he now lives in. At the same time, another enemy is using the situation to their advantage, following the werewolves at every turn, threatening to undo everything that Conner is struggling to obtain... But will he be able to bring Erin back from Filtiarn's grasp, or is it too late? And will he be able to stop the war against the humans progressing? And who is threatening to take over not only the humans, but the werewolves as well?
