Level Seven

Rate this book
Length: 9 hrs and 24 mins

A year after the radical Kilburnites thought they destroyed all AIs and reclaimed Earth for humanity, something malignant is growing in the ruins of the once great cities and no human has been able to get close enough to find out what it is.

On the other side of the solar system, Abby Gibson, daughter of the hero who saved Earth on Killday, is nearly killed in the cold vacuum of the asteroid belt by something she doesn't understand. Now, the stealthy object is on course to destroy the space habitat she calls home.

In Level Seven, the exciting culmination of the Killday series, AIs strive to evolve into a super intelligence and might destroy humanity in that pursuit. But could their hopes of achieving godhood actually lie with the nearly extinct humans they intend to eradicate?

A solid conclusion to an epic trilogy. The main character relationships slip into cliches but mortimer shines as the benevolent AI. engaging as an imagination of how we transcend physical limits. Very enjoyable even if it isn't at the same level as the first book.

The story continues on after the previous one. I don’t think one would be lost without having read them, but since I immediately went on to this book, I’m not sure. But I know book 2 did a wonderful job of bringing the reader up to speed if you hadn’t read book one. The book continues as a struggle between the AIs for domination, and the humans, who want to survive. But it gets interesting when the AIs sit down with humans to discuss the fate of humanity. What does it mean to be free? To be human? Would checks and balances similar to the Cold War nuclear deterrents, work? I did not expect the final solution. Great narration. note that there is some swearing, and references to a lesbian couple.

3.5 stars rounded down as ending was a little vague for what I thought was end of trilogy. Was also playing with ChatGPT, OpenAI and Brave browser search/answer with AI while reading this series and they were not kind in summarizing the books. Hope that browsing with private and over VPN was enough as do not want these guys coming after me.

Also, the song https://en.wikipedia.org/wiki/The_Fin... played three times while I reading these. Hope the universe is not telling me something.

I think that if I remembered more from the previous books, I would have enjoyed this more. AS it stood, it was okay. Just passing the time.

A truly satisfying conclusion to this 3-book Hard SF series.

It turns out the AI "Aggregate" weren't as exterminated as humanity thought. And the Aggregate have new plans...

Lots of conundrums for all the participating characters--the humans, the bi-ad human/AI pairs, and the AIs--and so many twisty turns in the plot. Despite this being hard SF, the author really kept it character-driven, which I loved. My favorite part, though, is that ending. Totally unexpected, and man I just loved it! Would love to hop over all the "messy middle bits" and live in that space :-) . Some of the humans being fans of "classic" SF shows was lots of fun, and greatly appreciated. Finally, I listened to this as an audiobook, and the narrator did a simply fantastic job.
