Unseen

Special Agent Will Trent has something to hide.
Something he doesn't want Dr Sara Linton - the woman he loves - to find out.
He's gone undercover in Macon, Georgia and put his life at risk. And he knows Sara will never forgive him if she discovers the truth.
But when a young patrolman is shot and left for dead, Sara is forced to confront the past and a woman she hoped never to see again. And without even knowing it, she becomes involved in the same case Will is working on.
Soon both of their lives are in danger.
