Complicate

The heart-pounding conclusion of the Deliver series.
Cole Hartman is a mystery. He works alone, sleeps alone, and satisfies his aches...alone. He hasn't touched a woman in seven years. No one will ever compare to the one who broke his heart. Until he stares into the seductive eyes of his enemy. 
He finally meets his match in the redheaded Russian spy. But she's a dangerous risk. His obsession with her leaves him only one choice. If you love something, let it go. If it doesn't kill you, hunt it down and take it.
