Colton's Secret Service by Marie Ferrarella

"Striking a Secret Service agent will land you in prison."

But the petite redhead with the cowboy hat and tire iron seemed unfazed by Nick Sheffield's words. The Secret Service agent had come to the tiny Texas town to unmask a potential threat to his employer a U.S. senator. Could his quarry be this captivating single mother who aroused in him a passion that was anything but innocent?

How dare this stranger show up and turn her life upside down! The last thing Georgeann Grady Colton needed was someone like Nick handsome, suspicious, irresistible. As danger and desire collided, Georgie knew she was travelling a treacherous road: falling for a man who was taking them both to the point of no return.
