Review of advance copy received from Author
I received an ARC and I am voluntarily leaving an honest review.
If you like a lot of action in your reading then you are in for a treat. The action starts in the 1st chapter when friends of Ryder are assigned with members of Polish troops who are trying to intercept a truck that is supposedly carrying weapons. They are successful and make the stop and report it up the line. After a few days, they discover that someone has quashed the report. Rodriguez notifies Ryder and he travels to Moldova to gather more information. While there he discovers that it is being shipped from America and he has an idea who is responsible. On arriving back he receives a message from Kendrick telling him of a meeting she is going to and isn't comfortable with how it was set up. Kendrick along with Thomas, another agent of CID, arrive on the scene and wind up in a shootout. Things look bleak because they are outgunned, but Ryder arrives and saves them.
The individuals behind the setup and the weapons shipments wind up being associated with Richter Industries, the same group that Ryder had to deal with in the last book. Richter is adamant that he wants Ryder killed. Follow along and learn what steps Ryder and his team had to take to protect themselves as well as what events happened as Ryder attempted to shut down the weapons shipments and how it all worked out in the.
This is a great story and well worth the read, don't miss out!

Execution Order
JT Porter
“Brother”, an operators definition is an unbreakable bond. Family and friends fall under that same definition.
Out of the gate corruption at the highest levels sets the stage for another action packed James Ryder thriller.
Vengeance with conviction and contempt for the antagonists who are plotting extraordinary action against the seemingly venerable.
With extreme brutality and conviction tables turn as Ryder unleashes his own justice.
Expect the unexpected, the antagonists won’t see him coming! Explosive, suspenseful and high octane action makes this a must read for those who appreciate vigilante justice toward those who think they are superior, unaccountable and untouchable.
I highly recommend ‘Execution Order’…JT Porter does it again!
Thank you for your sacrifice and service!

This is book four of the Ryder series. While it is a part of a series it does well as a standalone. The author gives enough of the backstory without becoming repetitive. I have absolutely loved the action in each one of these books. Veterans are some of my favorite people and should always be revered and never exploited. Ryder does an amazing job of helping veterans face various types of addictions and ptsd with Phoenix housing in place to help. No matter what he does to help, it seems as though there’s always the people on the outside. Trying to exploit veterans in the hopes of monetary gain. People are making billions of dollars selling illegal arms to enemy forces. Not if Ryder and his unit have their way!! Awesome book!! Can’t wait for the next one!!

Illegal arms sales by Richter Defence Systems continues, and this brings James Ryder and army CID Special Agent Jenna Kendrick together again. When ex comrades posted overseas identify American arms being supplied to terrorists, the elder Richter, Tobias, who has protection for his illegal activities from his own security team, and politicians and other Pentagon contacts comes into their sights!
There is plenty of action and intrigue in this story with so many twists and turns it is difficult to
see where the story is headed next. Ryder and his team from Phoenix House, one of the halfway houses set up by Ryder for injured vets, pursue the villains with force and technology, making for an entertaining read.

Relentless action from the beginning. As with the rest of the series thus far, a very well-written, suspenseful vigilante story that pulls you in and keeps you reading late into the night. Ryder is no longer questioning the morality of his choices and does not hesitate to remove undesirable, evil elements from society. He maintains his humanity by his care and protection of the vulnerable and especially the veterans he relates to. With this book, one does has to wonder where the line is between revenge and justice, though.

A very good series, read them all, you won't be disappointed. Ryder and his team are out for justice once again against the people who are harming veterans. This book will have you on the edge of your seat, so full of suspense and action. Were some surprises and twists that didn't see coming. Are you willing to risk everything for justice? Can't wait for their next fight for justice, Recommend. Received an ARC and this is my honest voluntary review.

Execution Order is a top story, I think it’s the best book in the series. Ryder gets a lot of help from his team, which is expanding with some new members with very useful skills sets. Packed with action and some interesting plot twists you sure want to read this one. Highly recommended. I received an ARC in exchange for an honest review.

It seems as though Ryder has met his match in this novel. It seems like all his well-planned attacks don't go exactly as he wanted them too. However, he doesn't quit. Neither does Richter. There comes the final showdown and then we're ready for Book 5! Recommended.

A Little Long
This 4th book in the series drags halfway through and suffers from some terrible villain dialogue. I do appreciate that Porter doesn’t rely on profanity, but this book would be better if it were 50 pages shorter.
