Jack

Once a protector, he has now become the hunter.

Jack Granger has done the right thing all his life, but when his life was turned upside down, forming Eidolon became his salvation. He built a team who are ready to fight beside him and die for the vow they all made—to protect the Queen. Once more his world is shattered by betrayal, his very essence is rocked as long-hidden secrets emerge, and the truth he's always believed about himself is shaken to its foundation.

She was tortured, betrayed, and abandoned.

Astrid Lasson was left for dead by the CIA. Rescued by a group of women who put her back together piece by piece, she became a member of the elite assassin group known as Zenobi. Just as she's found peace, a former foe finds her. Fighting to find the person who holds the answers to her past, Astrid finds her heart on a collision course with Jack Granger, the brooding, alpha, leader of Eidolon.

They will fight together to save Queen and Country

Thrown together to keep the Queen and the monarchy from falling, Jack must trust Astrid and open his heart to the sexy assassin with the past that's coming for them both. It takes all Jack's skills to keep everyone he cares about safe from a man who knows him better than he knows himself, and his focus away from the beautiful, but deadly woman who holds his heart in her hands.
