Obsolete Theorem, the FIRST book in my exciting Across Horizons series, is perfect for readers who love time travel, deadly creatures, wilderness survival, and unforgettable characters.
It wasn’t possible, but then it happened…
A Neanderthal’s 47,000-year-old remains are found in Spain. That’s not unusual, but positioned beside the woman’s skeleton is something that shouldn’t be there—a robotic drone. Lincoln Woodhouse has some explaining to do.
When confronted with the evidence, Lincoln cannot deny that the drone is one of his own models. After all, he routinely jumps his drones into the past to collect environmental data. The problem is, this drone shouldn’t even exist in Lincoln’s universe. Everyone knows sending a drone into the past creates an alternate timeline.
The implications of the discovery are staggering, and Lincoln is ordered to jump back in time to investigate, even though no human has ever done so before. Upon jumping, he and his team find themselves in a world of deadly creatures and savage beings.
Amidst the primeval chaos, Lincoln encounters Skyra, a woman unlike anyone he has ever known. She is a skilled hunter and vicious fighter. She is not human, but she just might hold the key to humanity’s future.

Here are a few of my favorite reviews of Obsolete Theorem:
"My favorite of Stan C. Smith's books (and I have read quite a few of his imaginative, always interesting, well-written and well-researched adventure series). This is classic SF adventure involving time travel into the past, and the creation of alternate timelines thereby, and the question of whether the time traveler can ever go home again."
- AJ Norton on Amazon
"To say Stan C Smith's new series hits the ground running is a huge understatement. Wow, does he know how to start a new series! Great story that runs at full pace throughout and is crammed full of tension. In essence, this is a time travel story but where others take us to great moments in history Stan C Smith takes us much much further to the time of Neanderthals."
- Chris Wells on Goodreads
"A new series, new characters and a whole new alternate universe. Stan C Smith and time travel go together like bacon and eggs. Can't wait for the next book!"
- Ann Keeran on Amazon
"This is my first book by Stan Smith, but don't think it'll be my last! It's a time travel story, but with a difference, since the time travelled back to is exactly 47,659 years in the past. A time when early humans and neanderthals co-existed."
- Maria on Goodreads
"Stan Smith's imagination is beyond what you've ever experienced. He's created another new universe for us to explore. Full of fantastical beings and intriguing detail, the action never stops."
- Lorraine on Amazon
"Wow what a mind blowing twist on time travel!"
