As with literally everything else, there's good YA and bad YA.

Check out Brandon Sanderson's "Mistborn" or "Skyward". I'd say they're both the "good YA" kind where danger is real (as much as any danger towards the protagonist before the very end of the book, obviously they won't get killed off in the first chapter) and the story relatively original. The world-building is excellent, though.

Dad was team Jacob all the way until the last book.

Donald Trump was unironically obsessed with ~~Edward~~ Robert Pattinson and Kristen Stewart's relationships. Had multiple crashouts on Twitter about it.

Sounds like this sweaty man has a shrine of every Twilight character, other than Edward, in his closet.

I mean if they're reading books in the first place you're probably already in the clear

I read a book with a school whose students were all boys whose name started with the letter A. It was literally a requirement.

I don't remember much but I do seem to recall they had a field trip to a "hole factory" so they got to take various holes as souvenirs.

Different kind of weird. Sideways Stories are goofy kids stories.

Twilight is fanfic with ageless vampires that choose to creep on high schoolers, and werewolves that fall in love with newborn infants.

Hey, Sideways Stories From Wayside School is great! And weird, but good weird. Twilight was the first thing I thought of when the COVID toilet paper crisis hit.

I loved those books as a kid! Probably my introduction to surrealism

What about a sentient bowl of petunias that is falling to its "death", again, and is the reincarnation of a rabbit, whale, fly, and cow? Or an android monk believing everything was the same shade of pink, making it too early to move from the spot it was on for fear of falling off a cliff, so it sat on the back of the (manufactured, organic) horse it was riding?

Yes, there can be multiple books that are weird or have weird stories. It doesn't have the be the weirdest one to still be weird.

Way to sideline things.

Your dad? Ben Affleck. Your mom? Neil Patrick Harris.

Might be a religion thing? The Twilight author is mormon iirc so she stays within the lines of what's okay there. So the dad might have considered non-mormon behavior to be inappropriate, even if the book isn't 18+?

Different parents have different sensibilities i guess, and different books have different contexts. I'm not very well read in this field at all, but at the beginning of one of the Tiffany Aching series of Discworld books, a subseries wrote specifically for young adults, a 13 year old side character gets beaten by her drunken father into a miscarriage after he found out she had a boyfriend and the main character has to bury the remains and saves the father from hanging himself.

Most of the series are Harry Potter level magic and adventure, but that was pretty shocking and I'd be a bit wary letting my 12 year old read that.

Honestly that sounds better than teenage angst and sparkly vampires.
