The video was everywhere – a viral sensation sweeping across social media.

A golden retriever puppy in Bilbao, Spain. It was placed on a series of different rugs, its fur shifting in real time to match the colors and even the intricate patterns woven into the fabric. The internet was in a frenzy, with hundreds of thousands of comments debating whether it was an elaborate hoax, a genetic anomaly, or something else entirely.

But Sam Reilly knew the truth the moment he saw it. This wasn’t a trick. Caliburn, his dog, shared the same genetic trait.

The golden retriever was an engineered chimera infused with human and octopus DNA. He was originally designed as a classified military experiment rooted in the legendary craftsmanship of the blacksmith Merlin, who designed King Arthur’s greatest weapons – Excalibur and Caliburn.

If the puppy was real, then so too was the danger that followed it.

The hunt for Caliburn’s offspring leads Sam into the depths of a forgotten cave – where he stumbles upon an antique Basque Astrolabe that shouldn’t exist. The discovery sets off a chain reaction, dragging Sam into a deadly conflict with a Secret Society that has been protecting a hidden truth since the Lewis and Clark expedition of 1804. Meriwether Lewis was murdered to keep the secret buried.

The question remains, can Sam work out what to do with the truth, before it gets him killed too?
