The best of the blog: Our 2025 reviews of Prometheus winners, finalists and more


Some of the most important, impactful and lasting articles posted on the Prometheus Blog this year were reviews.

Of the 120 posts published here in 2025, more than 10 percent were reviews – perhaps most notably, the latest review-essays in our ongoing Appreciation series devoted to honoring each year’s Prometheus Awards winners for Best Novel and the Prometheus Hall of Fame for Best Classic Fiction.

That may seem like a relatively small percentage of our posts, but it actually represents a major sustained effort – in terms of both time and thought – by Prometheus judges and other Libertarian Futurist Society members.

Certainly, it takes time and careful attention to write, edit, illustrate and publish the many posts focusing on awards news, LFS progress reports, author’s updates, essays, features and trend pieces about the influence of Prometheus-winning works and their authors on today’s culture and politics.

Yet it generally takes substantially more effort, insight and creativity to write thoughtful reviews of the most significant fiction nominated each year for a Prometheus Award. 

Here are the most noteworthy reviews we published in 2025, along with convenient links allowing you to read or reread any that spark your curiosity or interest:

Exploring the appeal and challenge of sequels with four Prometheus nominees: Machine Vendetta, Shadow of the Smoking Mountain and Best Novel finalists Alliance Unbound and Beggar’s Sky


By Michael Grossberg

Sequels are increasingly popular these days – especially within the fantastical or speculative genres of science fiction and fantasy.

Among this year’s recently announced five Prometheus Best Novel finalists are two sequels: Alliance Unbound and Beggar’s Sky.

Of the 11 2024 SF/fantasy novels nominated for this year’s 45th Best Novel award, four are sequels – including Shadow of the Smoking Mountain and Machine Vendetta.

Each sequel navigates a tricky balance between the fresh and the familiar.

Each can be enjoyed by newcomers as a stand-alone book. Yet, each is enriched by previous world-building and continuing characters that makes them rewarding for the author’s ongoing fans.

How each novel builds on its predecessors, or in some cases departs from them, varies in ways that help illuminate the appeal of sequels and their challenges.

Review: Alastair Reynolds’ Machine Vendetta blends space opera and a police procedural with kaleidoscopic world-building that explores liberty and diversity


By Michael Grossberg

A hidden threat to humanity’s independence and very existence energizes Machine Vendetta, one of 11 2024 novels nominated for the next Prometheus Award for Best Novel.

Both an epic space opera and a detective-driven murder mystery, the Orbit US novel by British author Alastair Reynolds is of additional interest to freedom-loving SF fans because of the intriguing implications of its quasi-libertarian world-building.

A deft SF police procedural with a twisty plot and credible characters who have legitimate reasons to mistrust central authorities, Machine Vendetta gradually expands into a wider drama about a desperate struggle to preserve humanity’s freedom.

Broadly embracing many forms of speculative fiction including science fiction, fantasy, dystopian cautionary tales and near-future political-tech thrillers, the diverse slate offers a wide variety and blends of genres, styles and themes – from the serious to the darkly satirical.

Most poignantly, this will be the last time that two authors are nominated for Best Novel because they’ve sadly passed away: Michael Flynn and Howard Andrew Jones.

Flynn, a two-time Prometheus winner for Best Novel, died in 2023 at 75.

Jones, a Best Novel finalist last year, died in January 2025 at 56.

SF2 Concatenation: Year-end SF/fantasy “bests” list overlaps with Prometheus Awards candidates, nominees

By Michael Grossberg

Each year, SF/fantasy publications, critics and readers compile annual lists of the past year’s best fiction.

Such lists can be helpful to examine for general readers and Prometheus Awards judges, because they bring to our attention or remind us of significant works worth checking out and that might otherwise be overlooked.

Consider, for example, the “Best SF books of 2024” list by SF2 Concatenation (Science Fact & Science Fiction Concatenation), a digital zine website and online archive focused on reviewing SF books, news and related media.

Of the eight 2024 novels recognized on the Concatenation “bests” list, half have figured in some way in the current cycle of Prometheus Awards judging for Best Novel – a relatively high degree of overlap.
