Unknown Threat is the first book in Lynn H. Blackburn's new Defend and Protect Series. This series focuses on the men and women of the Secret Service and I found it FASCINATING!! I'm a big fan of law enforcement and crime books, and getting to see the innerworkings of things I will never be a part of. So getting to learn a ton about the secret service and how they operate, and even just how their careers work was beyond interesting to me. Ms. Blackburn always does a phenomenal job of mixing intrigue, murder, danger with romance and God's truth. I highly enjoy the fact that she can write an awesome Christian Romance, that gives you all the feels, but still keeps it clean and Godly and Christ honoring. She writes flawed individuals who are trying to do their best in following God. She's not afraid to write about the hard stuff or the fact that, GASP, Christians are not perfect! Her books are always spiritually sound and leave you better than before you read the boo...
