Now. Interim clan leader Philippa is torn between spending her time guarding the body of the Ancient who possessed her former lover Vance, and following Vance so she can save him from the Ancient.
Gage can't get the blond human who saved his life out of his mind. The problem is, she can't get him out of hers either. And it's putting her in danger. Sacred trusts, broken. A legendary vampire wants more than absolution. He wants retribution. Forbidden passions, foretold. Forbidden trysts follow a forsaken twin vampire as he seeks out the human he shouldn't have feelings for. Slighted ones, return.
