Review of Unknown Threat by Lynn H. Blackburn

U.S. Secret Service Special Agent Luke Powell should be dead. Surviving an attack against he and his friend, Luke is on a mission to find out who is after him, and who killed three other special agents that were his friends. FBI Special Agent Faith Malone is assigned to oversee the case. Her tenacity of not losing a case has her determined to solve this one. Luke and Faith have to work together, and put aside their differences, to catch a killer before the killer catches them.

This is the 1st book in the Defend and Protect Series by Lynn Blackburn. She does a great job weaving together a thrilling story where the action doesn't stop until the very end. What I did enjoy was you had no idea who the "bad guy" was until the end. I think this kept the reader engaged throughout the entire story. I also enjoyed the crossover characters from her previous series and how they played a small, but integral part, in this book. If you enjoy a page turner that keeps you guessing until the end, you will enjoy the first book in this new series.
