To be sure. And your version is far and away better structured and clearer (though personally I'd leave out the flying pigs). It's just that it left out, perhaps through necessity, a couple of the things that interested me in the original.
Yes, I get that. But those things come across as pretty complex as they currently stand. I suppose if one main one was stream-lined it could work. But really to me, a query is really about the MC, the stakes, the obstacle, and not so much the fancy footwork. A clear, well structured query suggests the author is in command of their work, and can communicate it effectively, especially in 'blurb' form.
So again, in terms of sexiness of a query, the main opportunity is the unique hook. The time-travel complexity is pretty well worn, (I mean even Futurama's Fry is/was his own grandfather so.... ) and to be interesting they require a lot of words, so no place for that in a query. But flying sentient Pigs, well....that's pretty eye-catching.
Of course, it's Cli-fi's call.
ETA. Just to mention Cli-fi, the tenses in my sample aren't smooth enough, below is a bit better.
In the year 2200 Pigs do fly!
They came from a different place, a different time. They were our partners, our mentors, and our protectors in the topsy-turvy waters that was time travel.
But now the flying Pigs are been murdered. Somebody doesn't want this partnership to continue.
When the past-murder of a store-keeper becomes the front page news of the future, Juliet Carpenter, time travel critic and daughter of recently deceased scientist Dr John Carpenter, one of most foremost promoters of time travel, is asked by the Consortium to help restore order to a failing system.
But the Consortium isn't happy with Juliet's no-holds barred approach and she falls under the watchful eye of ruthless Timeline Corrector, Dorian Black.
Her only hope of containing the ongoing chaos rests with her budding friendship with eccentric but amoral billionaire, Henry Wilson. However, when she learns of Henry's role in the murder of her father, she is plagued by doubt and despair.
To save billions of souls, she must escape Black's watchful eye, overcome Henry's betrayal, find and stop whoever is murdering the remaining Pigs, and begin to restore balance to a unraveling time anomaly.
In doing so, she risks destroying a time paradox one thousand years in the making. A paradox that could permanently distort time itself, and put the very universe at risk.
