Yeahhhh... uh...
I mean, y'all know me. I'm always ready to claim genius for a work no one else liked. I'm always up for a meandering and apparently pointless trip through minutiae with a cherry on top at the end. But this one... I dunno. I don't see how it all fits together. I don't see what the giant has to do with the neighborhood. I don't understand why the giant had electric/storm-summoning powers. I don't get why it looked like their mother to one sister and not to the other, or what that was supposed to mean in the larger context of the interconnected life of the neighborhood and the fact that giant is a being of storms and war. I can't think of any mythology that fits the details I have, but I don't have enough of the unique details to piece together a complete image of the fantasy world and how or why it intersects with the real world.
If this were just a short burst of weirdness, I could shrug and say, "Yeah, it was weird. That's cool," but it wasn't short, and so now I'm left with this wide but shallow pool of characters, each with a little introductory paragraph, and a big inexplicable event that appears to have some sort of personal meaning to one of the characters but then explicitly doesn't (or at least the giant doesn't appear to recognize anything around her and thus is presumably not actually Fabiola's mother.) I don't know what to do with these bits. I've got pieces from like three or four different themed Lego sets, and I can put the half a pirate onto the crab legs and give him a part-spaceship-part-medieval-fortress to fly around, but that doesn't help me build any kind of coherent central image.

Let me try free association. I'm just thinking out loud here, writing thoughts verbatim.
Okay, so... giant woman. Repels men, attracts women. Largest viewpoint is a brittle-strong older sister with abandonment issues. Motherhood? Something about absentee parents? The hidden struggles of poor mothers whose kids feel abandoned and even abused but who really are just barely protected from even worse things by her unrelenting work out in the larger, scarier world?
But then we have electrical powers, storms, and that last line about a revolution. Um. Maybe Mom is a... a freedom fighter? Cops seem overall pretty negative, at least from the meta level. Maybe Mom is battling some kind of authoritarian regime? Drug lords? Getting pretty far afield here, and not a lot of motherly concepts. Is the mother thing a red herring?
But then why the emphasis on the giant's femininity, the story's overt focus on questions of gender? We've got older women losing their marbles, mindless aggression from the young males, a transgendered person or at least a transvestite, a creepy policeman hitting on the younger sister... And, biologically speaking, a mother is the one thing a man can never be.
But the giant doesn't appear very conflicted about her identity, and Fabiola has no crisis related to gender or sexuality, so those threads kind of fizzle.
Hell, I just don't know. I tried, y'all. I've been thinking here for like fifteen minutes trying to sort the story out and find something connecting it all, and I've got nothing. I don't see the pattern, and I don't know why.
