Nathan brings tales to life that are not only gripping but also rooted in real-world genealogical research.

Diahan Southard stands tall in the realm of DNA genealogy. Diahan has empowered countless individuals to decode their genetic legacies. With a background in microbiology, she's the guiding hand many need to navigate the labyrinth of DNA testing.

When these two powerhouses and the companies behind them (The Novel Guys (UK) and Your DNA Guide (USA)) joined forces in 2022, the genealogy world was set abuzz with sheer anticipation. And, boy, they did not disappoint!

The GSI Experience: Sawtooth Saga

The inaugural GSI Events: Sawtooth In-Person in February 2023 was nothing short of electrifying, with its exciting, promising new take on murder-mystery events. Held in Salt Lake City, Utah, participants were treated to a dinner-mystery-style event that was a fusion of Nathan's gripping narratives and Diahan's DNA expertise. Attendees were not mere spectators; they became sleuths, unraveling a killer's identity through the lens of DNA and genealogy. Inspired by one of Nathan's compelling novels, themselves set in Salt Lake City, the event was an immersive experience like no other.

But Nathan and Diahan didn't stop there. Recognising the growing demand and the global audience that beckoned, they transformed this experience into the GSI Events: Sawtooth Virtual. During the summer of 2023, participants from around the world joined in, proving that the thirst for genealogical mysteries knew no bounds.

And for those who yearned to unravel the Sawtooth mystery at their own pace, look no further! For, 26 October 2023 marked the launch of the GSI Events: Sawtooth On-Demand. Whether you're a seasoned genealogist or a curious newbie, this novel product promises a riveting journey.
