Psychological Thriller

BLURB

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?

REVIEW

Facing a terminal illness, cheating wife, and a company spy. I really enjoyed the plot of this book. It read really quickly, I liked the short chapters, and I read it in one sitting. A psychological thriller with a bit medical and contemporary fiction. Many people to consider for the defrauding and it kept me guessing. Full of family secrets, a mystery illness, and a company with an untrustworthy senior team. Plot covers the fears/concerns one may have of AI as it becomes more prevalent in our everyday lives.
