When your past comes back to kill you... For 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. Shaw offers to release him if he can recover a kidnapped boy, but the only witnesses are being murdered and Michael can't shake the agonizing memories of another child he was once sworn to protect. Meanwhile, police Inspector Sabrina Vaughn¿the woman Michael passionately loves but has been kept from seeing¿discovers a body that bears a striking resemblance to the missing boy. 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 past.
