Reading Weaponized by Neal asher (2023) was a marathon.

There are a couple of Asher’s novels I’ve enjoyed, The Skinner and The Voyage of the Sable Keech, for example, the first two instalments of the Spatterjay trilogy, published in the early 2000s.
I found those inventive and engrossing. I still think with fondness about the living ship. The Polity novels that intervene between those and Weaponized are set in a human universe ruled by AIs.
In Weaponized a bunch of human characters from the polity intend to colonize an outer planet. They’re all in their second or third century and are bored. They intend to go back to basics somewhere new.
Ursula Ossect Treloon is their leader. The plot is a relentless competition for superiority between the human would-be settlers, and the native wildlife.
Neither of them wins when both appear to be taken over by superior Jain technology, from yet another universe. The end is is circular, a mystery, when a fragment of Ursula is saved by the Polity mole.
Most of the story is the ‘science’ describing the adaptations that need to be made to continue the struggle to survive an ever evolving enemy.
And this is an evolution happening at a daily at most week’s pace. The actual plot was told with a series of one liners buried in the almost baroquely detailed descriptions of the technology. Non-stop action as the back cover promises.
By about a third of the way through, I was wishing for a bit of ordinary narrative, describing the settlers ordinary time. But if anything proceedings notched up, there was never any relief.
