Not Without Cause — Kay David

Meredith Santera is the leader of the Operatives, always putting the needs of others in front of her own. And that means she chose the job over a relationship with Jack Haden. Now her job is putting her in contact with Jack once again. But this time they're on opposite sides.

To save a friend. To protect a child. To end an evil. Most of us could not bring ourselves to do the unthinkable -- even if it was for the greater good. The Operatives do whatever it takes. Because of them, we don't have to.
