First to Kill - Andrew Peterson

First to Kill is the first novel in the Nathan McBride Series. This book is free with a kindleunlimited subscription.

Nathan McBride is an ex-marine sniper, ex-CIA agent, and now a private contractor. Nathan and his partner Harvey Fontana are pulled in on a special FBI operation because they aren't expected to play by the rules that the FBI follows. When it turns deadly, it's up to Nathan and Harv to finish the operation. The action is intense and the bad guys are really bad. Very highly recommended.
