Act of Valor by Dana Mentink

Violet Griffith works for the airlines as a TSA agent.  While checking in a flier she finds something suspicious and reports it to her supervisor.  He let the guy go through and tells her not to worry about it.  She can't let it go. So now someone is gunning for her. Violet's long time friend, Zach Jameson, is a K-9 officer.  He won't stand by and let anything happen to her.  He just lost his brother and is still reeling from that.  This the continuation of the True Blue K-9 Unit books. This is a great story. But I recommend reading the books in order to be able to completely understand the storyline.  

I received this book from Love Inspired Audio Books via Net/Galley in exchange for an honest review.  I was not compensated in anyway.
