FREQUENCY: The First Signal
A physicist follows a signal 4,500 years into the past. Someone has been waiting for him to arrive.
Cambridge physicist Ben Hartley has spent eight years chasing a 14.7 kHz frequency locked inside the limestone of the Giza plateau — a signal no one else believes in. When he finally decodes it, the signal doesn't just answer. It pulls him back to 2560 BC, to Egypt at the height of the Old Kingdom, where the Great Pyramid is still rising from the desert and an intelligence older than civilization is watching who arrives at first.
But Ben isn't the only one who made the jump. His former research partner Marcus has come too — with different orders, a different agenda, and the backing of an organization that wants what's buried beneath the sand. And somewhere in the space between time and stone, a 30,000-year-old system is about to ask both of them a question only one can answer correctly.
FREQUENCY is a fast-paced historical science fiction thriller for readers who want their ancient mysteries taken seriously — the physics grounded, the history accurate, the stakes genuinely high.
The Encoded Series — Book 1 of 3. The complete trilogy is written.
This book was translated from the original German book by the same author.

Seeking understanding
I have always enjoyed speculative “what if” stories blending pieces of known/imagined history with emerging science of today. The whole truth vs knowledge/power dynamic was amazing to watch unfold. Ben and Marcus represent so much of different the forces driving advancement. I simply loved the storytelling, thoughtfully connecting people, ideas and intents with the underlying urgency to understand the significance and meaning to the frequency. Partially resolved, I can’t wait to see where this story leads next.

Fascinating view on time travel
Egypt! The pyramids, built with technology over 30,000 years old! A pharaoh! Two scientists. Co-workers for 10 years. Enemies for another 8. What happens when they both travel from current time to over 5,000 years BC? Burial of pharaoh’s was not the primary purpose of the pyramids. They send signals to the ancient ones. Is man ready for what destroyed them? Sanders creates so many things to think about in this first volume. Of course, you’ll want to read more.

I really enjoyed this debut novel. It was fascinating to learn about the intersection between ancient and modern civilizations. The relationship and issues between Marcus and Ben gave the story a nice balance. I am looking forward to reading what happens next in Resonance.
Thankful for having won this book through Goodreads.

sci-fi time travel
A very interesting story. Makes the reader think. One question that comes to mind of several is how did the phone record the beings when they did not speak out loud?

So interesting you can stop bleary eyed reading it! What if I had a Time Machine…where and when to go? Quite a puzzle! Now your turn to leave 2026 and end up a long time ago!
