Rachel Gillig’s The Knave and the Moon Tops Genre Charts
The major debut of the week in speculative fiction was Rachel Gillig’s The Knave and the Moon (Orbit), the second installment in The Stonewater Kingdom series. Published by Orbit, an imprint of Hachette, the title debuted on all four major print lists compiled by Locus, ranking #1 on three of them. This performance highlights the continued commercial strength of established fantasy series and the power of strong series momentum in driving first-week sales.

Chloe Benjamin’s Under Story Debuts Strongly
Chloe Benjamin’s literary science fiction novel Under Story (Putnam’s) also made significant waves, debuting on three separate bestseller lists. Putnam’s, a division of Penguin Random House, continues to leverage its literary fiction strength to cross over into broader commercial categories. The simultaneous success of Gillig and Benjamin suggests a healthy appetite for both traditional fantasy and literary speculative fiction in the current market.

Spain: Backlist Titles Dominate Monthly Sales Rankings
Spanish media outlet El Placer de la Lectura reported that eleven titles have remained among the most purchased books for over a year, defying the typical dominance of new releases. These "longsellers" continue to grow through word-of-mouth and recommendations rather than launch marketing. This trend underscores a shift in consumer behavior where trust in established titles is outweighing the hype cycle of new releases in the Spanish-speaking market.

Circana BookScan Coverage and Limitations
Understanding US print sales relies heavily on Circana BookScan data, which estimates coverage of 80% of the traditionally published ebook market but is primarily used for print retail sales. It is important to note that BookScan figures are limited to US print retail sales—transactions at the register—and do not include direct sales by publishers or authors, which can skew total revenue figures for independent authors and large publishers alike.
Bertelsmann and Penguin Random House Financials
Recent financial reports from parent company Bertelsmann indicated that Penguin Random House revenues rose 1.3% in 2025 to €4.981 billion (approx. $5.76 billion). Despite this revenue growth, operating EBITDA for Penguin Random House came in at €704 million, down from €739 million the previous year, reflecting broader economic pressures in the global publishing sector.
