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.
