Kingpin Bear. The Agency, #4

The final battle with the Agency looms large as the last unmated shifter of the Underground embarks on his own quest for love. Jared Keppler has watched his team find their mates one by one, dealing with the challenges of love and duty. He has remained alone, until now. When the beautiful brunette comes running into his home with a dire warning, he and his team leap into action. But as things unravel around him, Jared comes to realize that his only constant, his mate, is hiding something from him.
Something that's tearing her up inside. Nadia Samson has just thrown the entire life she knew away, under the guidance of a hunch, a gut feeling that sent her cartwheeling into the arms of one big, hunky, Alpha shifter. That was the last thing she expected, but as they are forced to go on the run and into close confines with each other, the growing tension between them becomes harder and harder to ignore.
She feels herself falling for him, but tries to hold back. His life has been destroyed, and she knows something that would instantly turn him against her. As the struggle for freedom interweaves with his fight for love, Jared will have to use all the power's he's been blessed with to rescue the love of his life, defeat the enemy, and bring the Agency crashing down around him in a display of power and strength that only an Alpha possesses.
