BODYGUARD REUNION 

Narrowly escaping thugs who held her at knifepoint, lawyer Olivia Hammond turns to the man who once broke her heart, bodyguard Salvatore Santonni, for protection. However, when an anonymous caller reveals her boss has been kidnapped and will die if she doesn't comply with demands, she wishes she hadn't asked for help. Especially since the first order is to tell no one. But with someone determined to get something they think Olivia has, Sal won't back down. He can't let anything happen to the woman he never stopped loving. And as they uncover the truth, Sal and Olivia quickly learn that the threat is much more deadly than they ever would have guessed.
