The Digital Shamans

In the heart of San Francisco's tech scene, Evelyn Landry, a brilliant software engineer, feels a growing unease.  The algorithms she designs for NovaTech, the world's dominant social media platform, whisper of something ancient and unsettling.  Her pragmatic worldview clashes with the almost-forgotten stories of her Vietnamese grandmother, a woman who spoke of unseen forces and a world interwoven with magic. But when Evelyn discovers Project Chronos, a clandestine operation leveraging ancient magic to manipulate global consciousness, her skepticism shatters.
Together with Theodore Vance, a colleague haunted by a fractured family history, Evelyn plunges into a world of hidden code and digital rituals.  They uncover a network of tech billionaires and occultists—the Digital Shamans—who wield technology as a tool of enchantment, reshaping reality itself.  Their investigation draws them into a dangerous web of deception, pursued by shadowy figures who anticipate their every move.
As they delve deeper, Evelyn’s skepticism transforms into a reluctant acceptance of the magic she once dismissed. Algorithms become incantations.  Data streams become pathways to other realms.  And the Digital Shamans become sorcerers of the digital age.  Their path intersects with Dr. Iris Finch, Theodore’s estranged sister and a renowned anthropologist unwittingly entangled in the conspiracy.  Iris’s growing unease and Theodore’s desperate attempts to protect her create a tense triangle of trust and suspicion.
But the Shamans are not unified.  A rogue faction, led by the enigmatic Silas Thorne, offers a fragile alliance, forcing Evelyn and Theodore to choose between exposing the entire operation or joining forces to subvert a far greater evil.  Meanwhile, a tenacious tech journalist, Jenna Swanson, chases the whispers of truth, her investigation weaving closer to the heart of the conspiracy. 
The climax arrives with a high-stakes ritual on Mount Tamalpais, a battle for the soul of humanity fought on the digital and spiritual planes. Evelyn, Theodore, and Iris, now united by a common purpose, must race against time to disrupt the ritual, leveraging their combined knowledge of technology, anthropology, and the nascent understanding of techno-magic.
The ritual is disrupted, but at a cost.  The world awakens to the reality of magic interwoven with technology, a revelation that throws society into chaos.  The Digital Shamans are exposed, but the magic they unleashed cannot be contained.  Evelyn, Theodore, and Iris emerge as reluctant guardians, navigating a world forever changed, where the whispers on the wind, once dismissed as folklore, now hold the key to the future.  The question remains: can they guide humanity towards a future where technology and magic coexist in harmony, or will they succumb to the very forces they unleashed?
