‘For the first time in years, Perry believed in himself’ – One fine adventure!
Iowa author Craig A. Hart is both a writer and an editor: he has served as editor-in-chief for The Rusty Nail literary magazine, as manager for Sweatshoppe Media, and director of Northern Illinois Radio Information Service, an outreach that brought daily news and information to the visually impaired. His works have been published in The Orange Room Review, Voices, The Stray Branch, Red Poppy Review, The Mindful Word, Inclement, Right Hand Pointing, 7x20 Magazine, among others. In addition to writing fiction Craig has published self-help manuals on writing and critiques of other writers’ works. Now he continues his series with co-author SJ Varengo – An Onyx Sector Adventure - with Book 3 - YOU ONLY SPY TWICE.
The authors distill the plot well: ‘A deadly assassin strikes in Istanbul. A rogue agent defies orders. A shadowy conspiracy threatens to destroy Onyx Sector. And it’s all personal. Perry Hall, a battle-hardened Onyx Sector operative, is driven by vengeance in this spy adventure thriller. Teaming up with the fierce and captivating Adabelle, he hunts the notorious killer Flick through Istanbul’s gritty underbelly. Perry isn’t just fighting for justice—he’s fighting for redemption. From covert tunnels to high-stakes showdowns, Perry and Adabelle must outwit a ruthless enemy to survive, before time runs out.’ And so begins the intrigue!
The authors have a fine grasp on character development, a talent they expand with this new cast from the interstices of Europe and Asia. All the ingredients are there, but it is the chef’s hand at mixing them that makes this novel so successful. The book is relatively short – making for a fine evening’s read. Highly Recommended

Can the Dragon be slain?
There are many times in our lives that we wonder if the fear, the pain, the misery or just uncertainty will ever go away.
Sometimes we make one decision hoping that it will put an end to that torture, other times something happens that brings you closure in a way you never would have imagined.
Slay that Dragon the best way you know how, because if you don't it will eat you alive!

Perry, a loose cannon, goes off grid in search of revenge. With an unexpected turn of events, he finds himself in a precarious situation, teaming up with a formidable member of Onyx, Adabelle, who aids him in his search for Flick, his wife's murderer. Plenty of action with other agendas in the mix. Highly recommended.

Loved it!
Onyx is a hell of a team. Even in the worst of circumstances, they manage to figure things out. Zmaj is the creepiest of creepy. Ewww! Just the description made my skin crawl. And Flick? Well, I won't spoil the fun.
Great job guys! On to the next one!

Good for Perry. He has tenacity. This was crazy but I loved it. Seeming betrayal has everyone rethinking their life’s choices and wether to actually follow through with their orders. This book definitely kept me on the edge of my seat! I can’t wait to read the next one!

Entertaining fun read
No great plot. Actually very cliche. Rather fun when characters are attractive, rich, action heroes. Looking forward to Fleming’s reaction to Adabelle and her to him.

Chasing the devil, the end game for one of them, yet complicated by Code Grey is a stunning chase around the world. Will Onyx Sector survive or be left for dead? Third in the 5 star adventure Series.

A fun read!
I didn't know what to expect when I purchase this book, but I but the title was catchy so I grabbed it. I was pleasently surprised to find it had humor, suspence, romantic overtones, and adventure. A fun read!

A quasi Bond story
Great character development that grew through books 2 n 3. With the intro of Adebelle, I look forward to future stories and romance replacement for Perry.

You Only Spy Twice is a well written easy to read book. Follow the Onyx spies as they move through the hazards of Istanbul searching for a dangerous assassin.
