Definitely a step up from the previous version (or was that the two before…?)
A few tweaks still needed - grammatical messes (last few words of para 4) and there are a bunch of filler words (adjectives like "very") and other superfluous detail (the Geoff is "in a hospital" doesn't add anything, so could go). Also, the opening paragraph is internally confused; it implies Kelly is getting the devices to track the things already stolen, so it needs mentions that those two aren't the first, and that she tracks other new items.
Besides that, I believe (L. correct me if I'm getting this wrong) synoses are generally written present tense, even if the book is written past tense. It makes it stronger ("She did not expect it to work. But it did." v. "She does not expect it to work. But it does.")
The biggest thing, though, is the second paragraph.The order of those first three sentences is wrong. What you've said is "The finlter happened. Backstory to the filter happening." That needs to be rearranged into chronological and consequential order. "humans and magicals struggled to get along, humans became combative, magicals cut the humans off."
That will at least get to an overall shape that works, which can then be refined and tightened.
I'll also repeat one thing from the last version, which is some of the terminology, "Magical Folk," "Shadow," and "Queen of the Fairies" are generic names that imply a much younger audience than you're going for. There are equally generic but more mature terms you could use (e.g. Fey/Fae), and the antagonist needs a real name - probably the one Geoff gave his "imaginary friend" when first encountered, as a child, because that's how he will still refer to it, so something grossly innocuous. (Personally, I would have it hate the given name with a vengeance.)
