While I've read a lot of YA that's centered around donor-conceived stories, this was my first middle grade! Sometimes I feel like I have to really brace myself when a donor recipient parent writes a donor conception story, but I thought The Doughnut Club did a really accurate job with describing how a donor-conceived child may come to terms with finding donor siblings (I do hate the term diblings and actively cringed every time I read it).

My only real critique is that it read a little young for middle grade and it felt a little bit like free publicity for Donor Sibling Registry. Even though DSR wasn't mentioned by name, the description of the site and the fee match up with what Quinn describes in the book, and I don't love that readers could potentially be pointed that website's way (there's a thread from Feb. 2025 on r/donorconceived that explains why DSR is problematic). I also don't love how canonically Quinn has 16 donor siblings -- it's a super common trope in DC books that I'd love people to steer away from. It opens up a can of worms that I don't appreciate as a DC person!

Overall, I think it works as a great piece of representation for donor-conceived kids and works well as an introduction to donor conception for kids.
