Book Review - Dr. Mike Maden's “Drone Threat” is the last of the four book Drone series. I absolutely love protagonist Troy Pierce and his high-tech drone technology team. This was a very enjoyable book, good story line, suspenseful action, abundant and creative technology details and villains/bad guys everywhere. From the very first Drone book, Maden has created an interesting premise in the techno thriller genre with the understanding that sometimes the most lethal Black Ops warriors are those that are just out of sight and sometimes not human. His stories using high-tech drones to fight terrorism, terrorists and just plain evil is mind-boggling. The drones and other related systems are real and truly technologically 'amazing'. Yes they may only be prototypes or research concepts but they make the story just that much more intriguing, interesting and provocative. Tie the well explained technology in with a well developed storyline, interesting characters and lots of action and you got yourself a "unputdownable techno thriller." There are only a few things in life that make me go "hmmmm" and all four of Mike Maden's Drone books made me do that, especially this one, Drone Threat. Definitely worth a read but I recommend starting the series from the beginning with the first book, Drone. Hope Maden continues the Drone series.
