AI-Written Novels Flood Kindle Unlimited and Trigger Backlash in Publishing

Romance novelist Coral Hart says she has written 370 novels under 21 pen names using AI since 2025, earning "high six figures" on Kindle Unlimited, where the algorithm favors authors who publish at least monthly. Accusations of AI use are also costing writers lucrative publishing deals and removing them from prize shortlists. The report asks whether the industry can still reverse the spread of machine-written books.

Why it matters: Practitioners in publishing, content, and platform strategy need to understand how AI-driven output volume and platform incentives are reshaping the market and the reputational risks of AI use.
