Last Marine Standing starts off 10 years ago, when Samuel Larson was a young fourteen, being rescued from a horrific event. Fast forward, and you find out that Samuel Larson is none other than Aiden's friend, Sam. And he is about to go walkabout to find the four marines who saved him so many years ago. What he finds is more than he bargained for, with two of them dead, and the other two being hunted down. Sam finds himself in the thick of it all, with no real idea of what's going on, because Mac can't talk about it without being classified as a traitor to his country.
This is a fast-paced story that can be read as a standalone. Viktor and Aiden make an appearance or two, but nothing that would interrupt the enjoyment of this book. Personally, I loved it when they made an appearance, as it always satisfies to see 'what happens next'!
Sam and Mac have the attraction there, but circumstances as such prevent anything apart from hot and heavy going on. Still, you can always make time
