Andrea Bartz
In August 2024, Andrea Bartz joined Kirk Wallace Johnson and Charles Graeber as lead plaintiffs in a class-action lawsuit against the artificial intelligence company Anthropic. The legal action alleged copyright infringement regarding how the company trained its large language models. Plaintiffs claimed Anthropic fed its systems with pirated copies of their written work without permission or compensation. This move placed Bartz at the forefront of a growing movement among authors fighting against unauthorized AI training practices. The timing of the filing coincided with increasing public concern over data scraping and intellectual property rights in the digital age.
On the 23rd of June 2025, the United States District Court for the Northern District of California issued a ruling on the case. The court determined that Anthropic's use of digital copies of the plaintiffs' works constituted fair use under existing law. However, the judge also found that Anthropic had improperly used millions of pirated library copies during the training process. As the case moved toward trial regarding the specific issue of pirated library materials, Anthropic agreed to pay authors $1.5 billion to settle the dispute in September 2025. If approved by the court, this agreement would become the largest copyright resolution in U.S. history. The settlement amount reflects the scale of the alleged infringement and the potential damages involved.
Bartz released five major novels between 2019 and 2025, each published under different imprints within the Ballantine Books family. The Lost Night appeared first in 2019 through Crown, followed by The Herd in 2020 via Ballantine Books. We Were Never Here arrived in 2021, also distributed by Ballantine Books, marking her breakthrough into bestseller status. The Spare Room was published in 2023, continuing her streak with another Ballantine release. Her most recent work, The Last Ferry Out, came out in 2025, completing this five-book cycle over six years. This consistent output demonstrates a prolific
period in her career spanning multiple publishers and genres within the mystery and thriller space.
