Arc Manor Books, whose CAEZIK SF & Fantasy imprint published our 2025 Prometheus Best Novel winner, is having a special ebook sale.
Available through Sunday Sept. 14 at significant ebook savings are several novels by Prometheus winners – including Michael Flynn’s In the Belly of the Whale, the 2025 Best Novel winner.
“Michael Flynn’s In the Belly of the Whale won the Prometheus Award for Best Novel last month! This epic, hard science fiction tale unfolds aboard a colossal generation ship, where a decaying aristocracy faces rebellion after a mysterious death in the abandoned “Burnout” region,” publisher Shahid Mahmud said.
“It’s just $2.99 through Sunday (regularly $9.99),” Mahmud said, noting that no coupon is required to take advantage of all the current sale offers.
“Just click the button and cart will show the correct (discounted) price,” he wrote in an email to Arc Manor readers and their website-alert subscribers.
HARRY TURTLEDOVE
Another Arc Manor deal of interest is for the latest novel by Harry Turtledove, a 2008 Best Novel winner for The Gladiator and nominated again this year for his 2025 novel Powerless.

City of Shadows, Harry Turtledove’s new paranormal detective-noir series, has earned a “glowing Publishers Weekly review and consistently high ratings on Goodreads and Amazon,” Mahmud notes.
The current Arc Manor offer: 99¢ through Sunday (normally $9.99).
Also discounted (to $2.99) is the 2025 Nebula-nominated Sleeping Worlds Have No Memory by Yaroslav Bursokov.
“It follows exiled minister Shea Ashcroft as he confronts alien technology, political intrigue, and the unraveling of reality itself,” Mahmud said.
ANDRE NORTON AND MERCEDES LACKEY’S HALFBLOOD CHRONICLES
Finally, Arc Manor announced it has the contract for all four books of the Halfblood Chronicles. The first three were co-written by SFWA Grandmasters Mercedes Lackey and Andre Norton.
Elvenbred, the long-awaited fourth book left unfinished at Norton’s death, has now been completed by Lackey with Ben Ohlander.
Mahmud said that Arc Manor will be releasing one book each month in the series, beginning in June 2026, “culminating in the brand-new, eagerly awaited conclusion.”
For a limited time, the first book in the series is available for preorder through retailers for $2.99 (not through Arc Manor).

ABOUT THE PROMETHEUS AWARDS AND THE LFS
* Join us! To help sustain the Prometheus Awards and support a cultural and literary strategy to appreciate and honor freedom-loving fiction, join the Libertarian Futurist Society, a non-profit all-volunteer international association of freedom-loving sf/fantasy fans.
Libertarian futurists understand that culture matters. We believe that literature and the arts can be vital in envisioning a freer and better future. In some ways, culture can be even more influential and powerful than politics in the long run, by imagining better visions of the future incorporating peace, prosperity, progress, tolerance, justice, positive social change, and mutual respect for each other’s rights, human dignity, individuality and peaceful choices.
