Editorial Reviews


"Great story, Vargas kept me on the edge of my seat."
"I love it."
From Keragus:
I'm glad to make a return to Eden. The character development continues and so does the sense of adventure. I can also feel the author development in this story. His authenticity and passion bleeds though the e-ink on my kindle. 
I wouldn't know where I put this book if I was in charge of running a book store. Cyber punk, Sci-Fi, Sci-Fantasy, Thriller, Young Adult? It doesn't matter, I think some of the best stories go across multiple genres. 
If you are looking for something familiar but not the same as everything else, this is a great series to get into. It's hard to review the second book in a series. You don't have to have read the first but I suggest going back and getting a good foundation. I can't help but feel that the first 2 books are setting up a really good base for a solid story to come in the remainder of the series.

From the Author

Vernon's and Vargas' Story mix with this next installment of The Cypher Theorem Series. This was originally going to be only about Vernon's and Marie's honeymoon, and that was to be the title. All the beta readers that I had, along with my wife, wanted more. Then a little of this and a little of that, and BAM! new book. There where parts of this book, that were extremely fun to write, because even I didn't know where it was going to end up at times. Writing is a great experience to me, as well as connecting with readers. Enjoy!
