I loved every novella nominee I read this year. Most of them would work just as well, maybe better, for a young reader as any of the 650-page books currently marketed as YA or YA-adjacent. That's really the whole observation here. I'm not trying to relitigate the "why is YA bad" discourse that's apparently already all over TikTok -- I haven't watched any of it, and I don't need it to have an opinion based on what I actually read this season. I just want good books. Age category is beside the point.
The novellas earned their length. I went into this year's Hugo process already planning to rank Automatic Noodle by Annalee Newitz #1. I'd read it as an ARC last year and loved it. It's doing something genuinely distinct within the same broad territory as the rest of the category: identity, chosen family, and fulfillment, but through non-human, non-binary characters — robots and synthetic humans figuring out their own gender identities on their own terms (robot sex included, and it's funny). But the competition this year is genuinely stiff; every novella I picked up held its own. The Summer War by Naomi Novik, Cinder House, and The River Has Roots are all doing versions of the same thing from a different angle: twisting traditional fairy tale and mythological structures toward something that actually values female agency, love, and family — without tipping into sappiness or self-importance about it. (Cinder House in particular is spicy and genuinely weird, in the best way.) None of these books pad. Every worldbuilding choice and character beat is there because the story needs it, not because there's 500 pages to fill.
The doorstoppers didn't earn their length. I read Antonia Hodgson's The Raven Scholar earlier this summer: 650 pages, nine Guardian Animals, a map promising nine palaces the story barely visits. There are real ideas in there (a genuinely compelling possession theme, a court intrigue plot that could've carried the whole book alone), but they're smothered under too many subplots and minor characters, all competing for space and none getting quite enough to develop properly. Bloated and thin at the same time -- that's what happens when length substitutes for structure instead of following from it.
I saw the same failure mode, from a different angle, across Tracy Deonn's Legendborn trilogy. Book one set up something specific — a grieving, academically advanced 16-year-old navigating exceptional circumstances, grounded by her father and her own competence. By book three, that infrastructure is just gone: her father barely appears, the protagonist's sidekick goes from the most competent person in the room to a coma-bound plot device for someone else's arc, and thematically loaded material — root magic as gendered power, a trafficking plot involving children — gets raised and never examined. Where Hodgson's problem is too many ideas with no room to breathe, Deonn's is real ideas set up carefully and then abandoned as the series goes on. Different mechanism, same result: a book that's long but not full.
Age classification isn't the variable that matters. Some of my favorite reading this Hugo season was the graphic novel category — The Space Cat, written by Nnedi Okorafor with art by Tana Ford, aimed at a much younger readership than any of the above, and doing more with confident, uncluttered storytelling than a lot of the "adult" nominees managed at ten times the length. A good book knows what it's doing with the space it has. That's it. That's the whole thesis.
