This is the first book in the Templar Chronicle by Joseph Nassise, which I found on sale through BookBub.
Cade is the commander of Team Echo, just one of the teams of the modern day Knights Templar. He was attacked and left for dead by a fallen angel, and developed an ability that helps his team track down the evil that plagues mankind. He is determined to avenge the death of his wife and when a group of necromancers start destroying Templar bases and killing his fellow Knights, Cade knows that the Adversary is the one behind it. This is a very fast paced book, with lots of action and intrigue as well. I liked the twist of the Knights Templar story, and that it’s set in a modern day time period. I’m looking forward to reading the next book in this series.
