The startling events of Deadfall force the government’s heavy hand – prompting it to enact a harsh new law to rid the country of Pluribus.

Meanwhile, Greyson and his weary friends retreat to Colorado with the paramilitary group, Rubicon. It isn’t long, though, until Sydney and Nick are called on a mission, leaving Greyson with no choice but to patiently recover and train, ready to take on Pluribus whenever he may be called.

A year passes, and the country is still suffering from the fallout of the new law, with divided neighborhoods, nationwide protests, and renewed threats of secession. Even worse, Pluribus and its new Wolf teams have worked under the radar on a bold, crippling attack that they hope will send the country over the brink, spiraling to unavoidable civil war.

When Rubicon finally calls Greyson to mission, he must wield new ammunition and work with friends across the country – both old and new – to face the incredible threat. In a frenzy of explosions, deadly drones, and dazzling new technology, Greyson fights the terrorists in urban streets, snow-covered mountains, and towering skyscrapers in pulse pounding action that challenges Greyson to his core.

About the author

B.C. Tweedt

8 books29 followers
B.C. wrote the Greyson Gray Series to give today's children a real-to-life hero who is worthy of admiration - one who searches for truth, fights for justice, and dares to do good no matter the costs. Along with Greyson, B.C. added lovable characters with signature humor and a deep plot that grows with its characters both emotionally and intellectually. He believes modern readers are longing for powerful new stories that are both clean and exciting without any dumbing down.

He has a background in film, and many readers notice how his novels read like an action movie (and would make an amazing TV mini-series someday.) Just like a movie director, he prefers to stay behind the scenes; though he has greatly appreciated how many readers have fell in love with the series. He loved reading as a child, especially the Animorphs, Hardy Boys, and the Left Behind series, so it is a joy for him to give young readers another beloved series to add to their bookshelves.

The book that I read was Greyson Grey Rubicon by B.C. Tweedt. This book is a Fictional book. The author wants you to learn that even though you don’t think that it is right to do something you always have to take a risk.In Greyson Grey Rubicon Grayson the main character is know in colorado and one of his best friends has to leave the camp. Greyson has to face things that he has never faced in the past three books and having to meet the people that he has feared in the past three books.My character is Greyson the main character one of the words that I think that describes him is Daring the reason why I say that is because that is what he grew up and strives for. The second word is caring because even though he has seen things in the past he is one of the nicest kids in the book. The third word that I feel like matches Greyson is good the reason why I am saying this is because that is what he has been looking for all the way through the series he has been looking for what the G stands for on his hat that his dad gave him when he was a little kid before his dad left. A person that I feel like matches Greyson is Jackie Robinson the reason why I see this is because of seeing all the things that Jackie has done from being the first black person to play baseball to having to stay calm with people calling him names.One thing that I feel like the author is trying to show is that there are people that are so daring that they can be part of a team that the people in that team are the best of the best in the military and a kid is working with them. This book is one of the best books in the series and the best series that I have ever read this book shows so much action and is interesting on how people are actually doing in the world know. One thing that I can relate this book to in the real world is the terrorism in the schools and how kids are know going out and standing up for them self and others.I would definitely read this book if you like books like American sniper or books with action then read this books it has things from all different types of books romance,action ,mystery and more.

This is a good storyline. My recommendation is that you read the books that come before this one. It would make it much easier to understand what is going on in this story and who everyone is. That said there is a lot of action that takes place in this book. The characters are likable and you don't want them to get hurt. I hope to read more of the rest of this series. I received an ebook copy of this book from smith publicity.

BOOO, HISSS! There, I got that out of my system. Almost. I have just finished reading “Greyson Gray: Rubicon”, the fourth in a series by B.C. Tweedt. Mr. Tweedt is really good at cliffhangers. For a recap:

1. Greyson Grey: Camp Legend – 3-1/2 stars, Greyson discovers a terrorist plot at his summer camp. 12-year-old mixed with James Bond.
2. Greyson Grey: Fair Game – 3 stars – Greyson’s nemesis attacks the Iowa County Fair. “Oh, I can quit after this one…wait a minute….CLIFFHANGER!”
3. Greyson Grey: Deadfall – 3-1/2 stars, Greyson treks across America in chaos, trying to find his father. Another CLIFFHANGER! “But at least there are only 4 books in the series, I can do this!”
4. Greyson Grey: Rubicon – 3 stars…ummmm….CLIFFHANGER, and no 5th book, not even in the works.

This book was almost all “action”, lots of fighting and chaos and trying to figure out who the good guys are. In fact, they do not figure that out by the end of book four, saying to stay tuned for book five. But when I went to see when book five was going to come out, I found a statement from the author that he had gotten sidetracked by other projects, and it might be YEARS. By then, thankfully, I will have forgotten to care who the good guys are, or if now-15-year-old Greyson will work up the courage to lock lips with Sydney.

There were RINO (yes, “rhino”) crowd control machines, and millions of drones that could tell whether you were a friendly or not, and shoot you, and launch missiles, and…and…and… Worse than that, one drone, named LIAM in honor of a fallen teen compatriot, was continually being anthropomorphized, to the extreme, with “dimming hope”, “sensors grew frustrated”, admiring a beautiful community, and so forth.

Honestly, I get bored with “action” and fighting. Particularly 466 pages and 85 chapters of fighting. I would love to know how it ends up; does America have a civil war? Do the two evil teenaged assassins find Greyson once again? But it is not to be. 3 stars for a fun read, but ultimate disappointment.

This is a great book, but when will book 5 come out? I saw that the release date was 2016 and I'm here in 2020 waiting for book 5. I couldn't find anything online speaking of the release date except when Mr. Tweedt said on greysongray.com that book 5 may take "a year or more" to come out. That was in 2017.
