For the first time in Prometheus Awards history, our annual Best Novel award has gone to a posthumous work.

Michael Flynn, who died in 2023 at 75, was able to finish writing In the Belly of the Whale before his passing.
CAEZIK SF & Fantasy, a strong supporter of Flynn’s work, published Flynn’s last novel in 2024.
The epic science fiction novel, a suspenseful and insightful exploration of the complex challenges, conflicts and threats to liberty aboard a large colony ship two centuries into a projected eight-century voyage to Tau Ceti, has now won the 2025 Prometheus Award for Best Novel.
The other 2024 Best Novel finalists were Alliance Unbound, by C.J Cherryh and Jane S. Fancher (DAW); Cancelled: The Shape of Things to Come, by Danny King (Annie Mosse Press); Beggar’s Sky, by Wil McCarthy (Baen Books); and Mania, by Lionel Shriver (HarperCollins Publishers).
IN THE BELLY OF THE WHALE
Flynn’s last novel, posthumously published by CAEZIK SF & Fantasy, explores the complex lives, work, challenges and conflicts of 40,000 human colonists aboard a large asteroid ship two centuries into a projected eight-century voyage to Tau Ceti.
With its intricate world-building, believable characters in conflict, and profound grasp of human nature, the epic social novel freshens the SF subgenre of the multi-generational colony ship while raising deeper questions about the enormous difficulties of our species expanding beyond our solar system.
Beyond the usual technological and interpersonal issues of maintenance and survival that naturally arise, the colonists suffer from a dysfunctional bureaucracy, crew class divisions, and a traditional shipboard command structure that has calcified into an authoritarian hereditary aristocracy with enforced eugenics and a loss of focus on the mission goal.
Flynn’s kaleidoscopic novel is a wise cautionary tale and poignant libertarian tragedy about the underestimated challenges facing our species as we dream of someday establishing a beachhead of human civilization beyond our solar system.

Without sustaining the culture of liberty, self-reliance and voluntary cooperation that helped lift Earth civilizations to unprecedented levels of knowledge and prosperity, humanity may be doomed even if such ships reach their distant destinations.
Reflecting Flynn’s well-earned reputation for a high level of craftsmanship and a wintry poetic style, his last novel is an ambitious, multi-focused saga of power, decay and revolution embodying an enduring theme: The price of freedom (and survival) is eternal vigilance.
Visit the Prometheus blog for a full review of In the Belly of the Whale that illuminates how it fits the distinctive dual focus of the Prometheus Award on quality and liberty.
Flynn previously won two Prometheus Awards for Best Novel for In the Country of the Blind (in 1991) and Fallen Angels (in 1992), the latter co-written with Larry Niven and Jerry Pournelle.
Over more than three decades, Flynn was nominated nine times for a Prometheus Award, was recognized as a Best Novel finalist eight times and has now won three Prometheus Awards.
While it’s sad that Flynn is no longer here to receive this honor, the Libertarian Futurist Society is happy to have the opportunity to recognize the late, great author in the Best Novel category one last time.

Coming up: The 45th annual Prometheus Awards will be presented online at 2-3 p.m. Saturday Aug. 30 (Eastern Time) via Zoom, with leading libertarian thinker and fantasy novelist David Friedman as a guest presenter.
A web link will be provided on the blog (in the weeks before the event) to access the Zoom awards ceremony, which will be open to all Libertarian Futurist Society members and the public.
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 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.
