Through tight prose and tension-filled action, Nessi's world building is fantastical yet all too real—The Source will leave you teetering on the edge of the abyss and wondering if hope is alive or lost. - Gary Schanbacher, award winning author of "The Waterman".

The Source was amazing! I love that the main characters are five women scientists who know their stuff, are adventurous and who work together…no egos getting in the way. The excitement ratchets up quickly as "things change" and the consequences are world-threatening. Bring on Book Two! - Toni M.

The Earth is breaking. Around the world, scientists begin detecting subtle but alarming shifts in the Earth's rotation and tilt. At first the anomalies seem unrelated, isolated data points buried within oceans of scientific measurements. But as the disturbances grow, a team of international women scientists discovers a pattern that points to something far more profound.
Drawn together by a mystery that spans continents and centuries, they follow clues hidden within some of humanity's most ancient structures. What they uncover challenges long-held assumptions about Earth's history, its stability, and humanity's place within a much larger story.

As natural disasters intensify and the evidence becomes impossible to ignore, the team finds itself in a race against time. Powerful interests ignore the truth, while the forces driving the planet toward instability continue to grow. With the future of civilization hanging in the balance, they must solve a mystery buried deep in humanity's past before the Earth reaches a tipping point from which there may be no return.

Blending cutting-edge science, ancient mysteries, and global adventure, The Source is a suspenseful techno-thriller that explores what happens when modern science confronts questions humanity was never meant to answer.
