I have some mixed feelings about this book. 
The mmc is a hot hockey player billionaire that is also a single Dad and hires a bodyguard to protect his daughter because there are death threats against her. 
The mfc is a former FBI agent that is now in personal security and knows how to defend herself. 
The daughter of the billionaire is 6 bratty, full of mischief and has the worst timing ever. 

What I did not like spoilers! : 

The female lead had to leave the FBI because she was sexually assaulted by her boss. His word was against hers and nobody believed her. 
She then was again sexually assaulted in this book. And did not go to the police. I don't like what that suggests women to do in these instances. 
She comes across as weak the whole time. 
She never really does the job she was hired for. All she does is playing his girlfriend don't get me wrong the romance in those parts is great but it feels like she was never supposed to be the person to protect someone. Because she is always the victim.
