The Sin Factor: DC Bad Boys Series, Book 1 (Unabridged‪)‬

In this intriguing mystery, Jeffrey Sinclair has a thief in his midst. One of his highly sensitive prototypes has gone missing, and he's on a timeline to recover it to avoid bankruptcy. In his search he finds himself in the middle of a deadly game where trust is a luxury he can't afford. The last person to have the devices has been killed and now his only link to the stolen property is the man's widow.

Avery Montgomery is a woman heroes marry and protect for life, and Sin's never been the protecting, hero type - not like her dead husband. When her life is put in danger, Jeffrey strives to keep her safe, while following the twists and turns to uncover the truth before it's too late. Unfortunately, time spent with Avery makes him yearn for the impossible... to be her hero.
