A.I. Is Writing Fiction. Publishers Are Unprepared.

For months, speculation has been building online that a buzzy horror novel, “Shy Girl,” was written with the help of A.I.

The novel, about a desperate young woman who is held hostage by a man she met online and forced to live as his pet, was self-published in February 2025. The book quickly found an audience among horror fans, and Hachette published it in the United Kingdom last fall and planned to release it in the United States this spring, billing it as “an unapologetic, visceral revenge horror novel.”

Earlier this year, Max Spero, the founder and chief executive of Pangram, an A.I. detection program, heard of the claims about “Shy Girl” and decided to run a test of the full text. Its results indicated that the book was 78 percent A.I. generated.

“I’m very confident that this is largely A.I. generated, or very heavily A.I. assisted,” said Spero, who posted his research on X in January.

The Times also analyzed passages from the novel using several A.I. detection tools and found recurring patterns characteristic of A.I. generated text, like gaps in logic, excessive use of melodramatic adjectives and an overreliance on the rule of three.

In the months since “Shy Girl” was released in Britain, more readers voiced their suspicions online that the writer relied on A.I., citing nonsensical metaphors and odd, repetitive phrasing. As a chorus of allegations built online in late January that the novel was A.I. generated, Hachette stayed silent.
