Unknown 9: Revelation: Book Two of the Genesis Trilogy

Rate this book
The mystery, intrigue, and globetrotting suspense continue in this second installment of the Unknown 9: Genesis trilogy. After escaping from a watery dungeon in Venice, astrophysics PhD candidate Andromeda "Andie" Robertson and investigative reporter Cal Miller are whisked to Bologna by a member of the mysterious Leap Year Society. A deadly confrontation with the Society's bitter rivals, the Ascendants, sends Andie and Cal on the run once again, desperate to solve the Star Phone puzzle so they can reclaim their lives and rescue their loved ones. ​Brilliantly juxtaposing a modern-day thriller with a historical search for a missing physicist, REVELATION probes ever deeper into the mounting mysteries surrounding Andie and her past. What is the source of her strange hallucinations? What are the true origins of the Leap Year Society and the Ascendants? How are her mother and her mentor, Dr. James Corwin, involved? From Italy to India and New York to Buenos Aires, Andie and Cal risk their lives to probe a secret world hidden in plain sight, drawing closer to answers that will determine not only their own fates, but who controls a new frontier of knowledge. From the author of the bestselling Dominic Grey novels, Genesis is a mind-bending thriller about how far two people will go for answers, and to save the ones they love.

The Review

Much like in his first book in this series, (and in every book I’ve read from this amazing author), this second entry into the multi-media series does an amazing job of crafting the perfect pace for this narrative. The air of mystery and suspense that comes from this cat and mouse game both in the past and the present is fantastic to read, while the author's writing style definitely invokes a cinematic quality to it.

The layered approach to the narrative the author takes creates a truly tense and mysterious atmosphere within the novel, and the character growth develops a rich plot that spans the entire globe and beyond. The style of this narrative and its overall contribution to the multi-media series makes this novel even more engaging, as it creates a mythology that not only readers can get lost in, but evokes nostalgia for fans of properties like Assassin’s Creed, The X-Files, and The Da Vinci Code.

The Verdict

An engaging, entertaining, and highly action-packed thriller and sci-fi novel, author Layton Green’s “Unknown 9: Revelation” is a must-read novel of 2021. The story is intense and has a steady progression for both the narrative and characters that readers won’t be able to get enough of. By the book’s end, the shocking revelation of the mysterious “Archon” will have readers floored and eager to learn more about the next chapter in this series.

Such a great read. I loved the first book that I couldn’t wait to read the 2nd book from the trilogy. I’m happy to know there will be a 3rd and final book as the ending left me in shock! Highly recommend!

Continuing the dangerous mission that befell them, Cal and Andie narrowly escape the Ascendents in Venice and follow the clues on the Star Phone around the world in hopes of finding Andie's beloved PhD advisor who has disappeared, Dr. James Corwin and defeating the Ascendents who destroyed Cal's life and are holding Andie's mother.  The clues in the Star Phone were laid by Dr. Corwin, part of the Leap Year Society, spent most of his life trying to find Ettore Majorana who developed a device, The Enneagon that would change the world and how we understand it.  However, the Ascendents will stop at nothing to find the Enneagon as well. 
Unknown 9: Revelation is the second book in the Genesis Trilogy.  You must read book one first in order to grasp the full scope of the story.  Just like the first book, Revelation is an addictive thriller, impossible to put down.  The story picks up right where it left off in Genesis.  I absolutely love the complexity of the puzzles on the Star Phone and how they lead Andie and Cal to unique places with hidden histories all over the world.  Added points of view from Dr. Corwin on his mission in the 1970's and two members of the Ascendents round out the story and help put more pieces of the puzzle in place.  Written with extreme detail and care for plot, characters and imagination, Revelation is a fast-paced adventure that I can't wait to continue in the last part of the trilogy.

I highly recommend reading the 1st book in this trilogy, as Revelation will not make much sense without that context. This book is highly interesting and keeps you on the edge of your seat.

An excellent second part

This series doesn't disappoint, even if a couple of the reveals are slightly predictable. The Unknown 9 expanded universe is one of the better ones out there, and the story and characters are solid and interesting.
