Zac McBain is on a mission to a place that doesn't exist - a place that disappeared thousands of years ago. The source of the Specus Argentum--the only silver that can harm the Cruors, is sought by not only Zac and the Ancients, but Dac Valerian as well. Hidden deep in the rainforests of Honduras, the present day town of La Nahuaterique, Faith Hannah is on a mission, both humanitarian and personal. Her medical mission is prompted by her wish to escape the problems that assail her in London. She never expected to be kidnapped and discover a whole supernatural world around her own--and she certainly didn't expect to feel such a sudden, intense need and longing for one of them. As soon as Zac sees Faith deep in the woods, he's lost to her. In the middle of a hard fought battle for the Specus Argentum, the passion fate has decreed between Zac and Faith begins to consume them. But the impending war between the Cynn Cruor and Scatha Cruor comes to a head. Secrets are unearthed, loyalties are doubted... and love must struggle to prevail.
