Landing a publishing deal was a dream come true for Jack Strange.
"It was incredible. I'd had so many rejections along the way," he says.
"So when someone said yes, I cried because it's everything I ever wanted."
Before Jack published debut novel Look Up, Handsome, he'd written other, self-published titles.
But he felt an entirely different emotion when he found out that those works had appeared on LibGen - a so-called "shadow library" containing millions of books and academic papers taken without permission.
An investigation by The Atlantic magazine revealed Meta may have accessed millions of pirated books and research papers through LibGen - Library Genesis - to train its generative AI (Gen-AI) system, Llama.
Now author groups across the UK and around the world are organising campaigns to encourage governments to intervene.
Meta, which owns Facebook, Instagram and WhatsApp, is currently defending a court case brought by multiple authors over the use of their work.
