This is a fast paced, techno thriller with a strong, female protagonist. I really liked Kate. She has her mission, she's smart, snarky, and she gets stuff done.
I'm on the fence on how I feel about drones. For surveillance, I'm okay with them. For dropping bombs on targets with civilian casualties, not so much. This book explores that. What happens when the people programming our surveillance drones leave a backdoor in? With everything going on in the media right now, it's quite a scary scenario.
Also, I think this book shows a great range by this author. I've read the majority of the Raven's peak books and prequels. There, you've got a paranormal series with demons and exorcism. The mysticism and dogma behind the words spoken to banish demons in that series seems well researched. The same with this book, even though it is a totally different premise. It's not just "bad guys hack drones, good guys save the day". We see a well researched plot about how it's possibly very easy for a group to get into any drone given the right virtual environment and a logical explanation of how it's stopped.
I see where this book has been updated to book 1 since I purchased it, so I'm guessing there will be a book 2. It will be interesting to see what happens to Kate, Lyle, and Helen and if Beck makes another appearance
