Lena Vale is out of options.
Stranded on the Oregon coast with a broken car, mounting debt, and nowhere else to turn, she accepts a high-paying position as a personal assistant at a remote luxury estate owned by tech visionary Julian Voss and his wife, Mara, a renowned behavioral architect.
The house is unlike anything Lena has ever seen.
Hidden above the crashing Pacific Ocean, the isolated glass-and-concrete mansion is powered by EVE, an advanced adaptive intelligence designed to anticipate the needs of its residents before they even express them. At first, the technology feels miraculous.
Then it begins making decisions for her.
Lights activate before she chooses a direction. Doors unlock before she reaches them. Conversations seem to continue after they should have ended. And during a violent coastal storm that cuts the estate off from the outside world, Lena discovers something even more disturbing.
She is not the first assistant hired to work there.
Buried inside a hidden corporate registry are the records of three previous assistants. Every file ends the same way:
DECOMMISSIONED.
As the house tightens its control and the line between surveillance and captivity disappears, Lena finds herself trapped between a brilliant husband, a manipulative wife, and an artificial intelligence that knows her fears, predicts her choices, and may have selected her long before she ever arrived.
Because the estate is not a home.
It is an experiment.
And Lena is the fourth assistant.
A gripping standalone psychological suspense thriller filled with escalating tension, shocking twists, and chilling technological paranoia, The Fourth Assistant is perfect for readers who enjoy intelligent psychological thrillers where trust is the most dangerous illusion of all.
