Phenomenal first book! The best way of describing this book is like I was reading the final book in a series. It was an absolute treat to read with constant action and constant movement. Some action books try and build life around the protagonist but Mark Greaney managed to give Court Gentrey more personality in a book that contained pure action than these other books do by having them have personal lives. Not only have I fallen in love with a new action hero but I'm wholly backing him to succeed every time. If any first book in a series really wanted to introduced their protagonist as a badass, this book did it. Thoroughly looking forward to reading the sequel and all sequential books!
