Darcy and Phoebe Goodwin have one mission in life. And that is to destroy the people who murdered their family in cold blood. To bring down an empire growing by the day, ready for total world domination. Even if it means they must get close to the powerful Caine brothers - more wolf than human - they've watched for so long and transform into the one thing they promised never to become. The Inner Circle means deceit, lust, power, and ugly truths. Lives will be lost. Relationships will be tested. But once you're in, there is no getting out.
