Interesting start. But needs work to become a coherent and sustaining series. ( )

Product Description
From the author of the international bestseller The Squeamish Vampire and the DC Coven series comes a time travel story where a young man with MacGyver-like skills must face ruthless ancient warriors. Good thing his companion is a mysterious young woman with exceptional fighting skills. Too bad she has her own agenda.
When Duncan decided to take a month off and travel around Europe, he never imagined where he would end up. Or when.
He wakes up in a world utterly different than the one he knew—a world with no GPS signal and no internet connection. Struggling with the societal norms, injustice, and inequity of the time, Duncan reluctantly accepts the help of a beautiful young woman, Alana, and her father.
With the threat of an attack looming over their heads, Duncan must use his knowledge of modern chemistry, physics, and cyber technology to stop an invading army and save an entire town along the way. Will he find a way to protect them and return home or die at the hands of the ruthless Celtic warriors?
From the Author
A state-of-the-art RV, drones and Celtic warriors are but the tip of the iceberg.
About the Author
Andrei Saygo is an avid reader, dreamer, and father. In his other life, he gets to do some fantastic things in cybersecurity.
He thought about writing a book for a long time. His work in cybersecurity flew him all over the world, offering him the opportunity to meet people from different cultures and it helped him gain some wonderful experiences in the process. But it wasn't until after his daughter was born when he finally sat down to type something out.
During the few quiet moments, late at night, the screen sat there, inviting Andrei to share a thought or two. That's how all books start, with an author staring at a blank screen, ready to share a dream with others.
"Inside the pages of this book, readers will find my dream," says Andrei, "I hope you will enjoy it."
