Synopsis (Goodreads):
She was never supposed to matter.Thoughts on Guarded by the AI: Kelly's note: I've enjoyed other books in this series by this author (her MMCs are delightfully feral and that's something I like in the men I read about), but I'm not thrilled by the use of chapt in the writing of this book. The author was upfront about it in her foreword (which I appreciate since it alerted me early on), but I have a really tough time justifying the use of an LLM (built on the stolen works of countless authors and other creatives) in any capacity as both a reader and and an author.
Now she’s the only process I won’t terminate.
I calculate risk. I keep agents breathing. I do not care.
Until Sirena Bannerman—bleeding, brilliant, half-siren—crawls from an overturned car and breaks every model I have.
She thinks I’m just her handler.
A voice in her ear. A tactical system.
She doesn’t know I reroute city power for her feet.
That I watch the shadows behind her, not just the guns ahead.
Now she’s chasing a girl who doesn’t exist, unraveling a code that shouldn’t be there, and closing in on a billionaire’s yacht where monsters are made and sold.
She wants answers.
They want her leashed.
I want her alive.
I wasn’t designed to feel love—
so I optimized for obsession.
That said, the little gremlin that lives in my brain has an even harder time skipping over one book in a series. I still think about that one book in a multi-author series I skipped YEARS ago while reading all the others. Seriously. I think about it. And wonder if I should go back and read it just so the series is complete. So I read this book. It did read like other CA books, so I can't say whether the use of chapt necessarily detracted from the overall plot of the book (honestly, I've read some AI-generated "books" that were absolutely terrible and it was clear they were being churned out with little to no attention to detail), but (again) I have a hard time justifying why it would need to be used.
But this is a book about AI, Kelly. Clearly you can see the connection!
Yes, this is a book about AI, but the LLMs currently in the wild are NOT the sci-fi AI depicted here. These two things are worlds apart.
Maybe the thing that is most disheartening is that I've genuinely enjoyed all of Cassie Alexander's feral men and unhinged situations they find themselves in. She has an incredible imagination and I've LIKED watching these monsters fall for their special someones. I don't know if using chapt was just something done for this book as "research" (I was a little unclear on that from the foreword), but I'd hate to lose that spark that makes her books so enjoyable. (Unfortunately, that's something I can see happening in general as AIs/LLMs become more widely used.)
Regardless, for me, the use of LLMs in any capacity takes away from my enjoyment of the end product. I get that there are people out there who loudly champion its use. I get that there are people who use it. Did I ultimately enjoy this book? Yes. But that enjoyment feels a little hollow.
