From internationally bestselling author Daniel Kalla, whose thrillers are “impossible to put down” (Amy Stuart, #1 bestselling author of Death at the Party), comes a razor-sharp psychological thriller about a CEO whose carefully curated life is falling apart. His wife is cheating, someone is stealing from his AI company, and he’s just been handed a fatal diagnosis. He’d end it all, if only he could trust his own reality.
Liam Hirsch has it all—a loving family, a thriving career as CEO of an AI company, financial security, and a bright future. But when he’s diagnosed with a terminal illness, just weeks after discovering his wife’s infidelity, his perfect life unravels. As he grapples with his fate, he prepares to face his final days on his own terms.
However, unexplained events inside his company make him question everything—including his diagnosis. In a world of deepfake videos, synthetic voices, and digital deception, couldn’t these technologies be weaponized against him? What if nothing is as it seems?
With time running out, Liam turns to Andrea DeWalt, a private investigator contending with her own feelings of betrayal, to help him uncover a conspiracy that threatens his life, his family, and their future. In a world where nothing is as it seems and every digital footprint can be manipulated, who can Liam trust?
With artificial intelligence continuing to develop at a rapid pace, it is people like Liam Hirsch who package it for everyday use.
Sometimes, however, opening the door to such technology leads to unexpected consequences. Author Daniel Kalla delves into the world of AI in a psychological thriller, skating the line between fact and fiction in The Deepest Fake.
Liam’s company is poised to launch a new app that creates an avatar of a chosen subject, with the ability to converse in a manner similar to video chat. While the details are supposed to be secret, a leak generates controversy.
Liam’s carefully crafted world suddenly gets upended with a terrible medical diagnosis alongside a report from a private detective about a personal betrayal.
As the storyline unfolds, the author illustrates how easily AI can infiltrate our lives in unexpected ways. Liam relies on the PI to unravel the pieces, uncovering a shocking conspiracy.
The Deepest Fake tells a cautionary tale about AI and its ability to do harm.
