A 50,000-year-old warning. A deadly conspiracy. The fate of humanity at risk.

When Daniel Rossler uncovers an ancient letter--written over 50,000 years ago--it warns of unseen messengers of death that walk the sky and the awakening of a monstrous force. At the same time, the Rossler Foundation's most advanced data system detects a disturbing rise in global instability, pointing to an impending disaster no one can explain.

As Rossler and his team investigate, they uncover shocking evidence of an advanced prehistoric civilisation--one that may have harnessed technology far beyond what the modern world believes possible. Their journey takes them to a remote and treacherous landscape, where hidden truths lie buried alongside ancient ruins. But they're not the only ones searching.

Eligo Rarus, a shadowy organisation of the world's most powerful elites, has its own plans--plans that could reshape society forever. As ancient warnings and modern conspiracies converge, Daniel and his team must race against time to stop a cataclysmic event that could rewrite history and end the future.

The Skywalkers is the fifth pulse-pounding installment in JC Ryan's acclaimed Rossler Foundation Mystery series, where the mysteries of the past clash with the threats of the present in a relentless battle for humanity's future
