Night Moves: Nighthawk Security, Book 4 (Unabridged‪)‬

If you’re in his sights...

County social worker Natalie Dunn discovers a horrible secret about the father of her juvenile clients. The man not only killed one woman, but Natalie suspects he’s killed several others. She plans to go to the authorities, but before she can, the killer turns his sights on her. Fearing for the lives of this man’s children, she removes them from their home and calls in former US marshal Drake Byrd of Nighthawk Security to protect her and the children and help her prove their father is a ruthless killer.

...you’re as good as dead.

As they investigate, Drake learns the father is a former elite sniper and assassin, and he has done a professional job of hiding any evidence of his wrongdoing. Drake vows to protect Natalie and the three children - all of whom he has come to care for - putting everything on the line for them. When bullets start flying, can he save them all from a certain death?
