[Sabrina Vaughn 03] • Promises to Keep

For three years, Michael O'Shea has been forced to act as a personal assassin for Livingston Shaw, the cold-blooded puppet master who controls the remote bioweapon implanted in Michael's back. When Shaw offers to release him if he can recover a kidnapped child, Michael works with every ounce of his being to put the pieces together before all the witnesses are murdered.

Meanwhile, police Inspector Sabrina Vaughn-the woman Michael passionately loves but has been kept from seeing-discovers the body of a little boy that bears a striking resemblance to the missing child. Against all his instincts, Michael must draw Sabrina into his life as one of the world's most notorious assassins if he's to overcome the legacy of his bloodthirsty past.
