Star Witness

Mackenzie Winters spent years building a life in Witness Protection, but when someone shoots at her, she fears her cover has been blown. Could the brother of the drug lord she put away be here for revenge? Mackenzie must rely on her handler's twin, world-weary Delta Force soldier Aaron Hanning, to protect her. Aaron doesn't want to be anyone's hero, but he can't let this brave woman die. Now, with danger stalking them, they'll have to make a daring choice that means life or death for them both.
