Hazel dear, if you and I had been the same age (and, you know, if you were real), I wouldn't have cared if you were Goat Girl, Skunk Girl, Earthworm Girl, whatever, I would absolutely have wanted to be your friend because you are awesome.
This was so sweet and a really enjoyable read. Definitely the kind of middle grade I think anyone could enjoy, and the kind I'd love to put in a lot of kids' hands. Hazel is a great character, and I appreciate that she's a little bit of a weirdo without veering into "not like other girls" territory. Because in middle school, it really doesn't take much to be "not like other girls" (I speak from experience!) so it doesn't feel as trite. She's bright and curious and big-hearted, and even when she behaves a bit poorly, it's never out of brattiness or meanness, but rather uncertainty or just simple awkwardness. I really felt for her as she tried to grapple with the fears around her mom having another baby, after the two heartbreaking miscarriages. And I loved that even when kids made fun of her, she never let that make her think she had to change herself to please them.
Her family is lovely, too, and I appreciated how straightforwardly the author approached their situation, regarding Hazel's father and the babies and such. I also thought the handling of the trans girl, Carina, was done quite well. There's no long, soapboxy explanations, and the reader can see right away that Carina being allowed to be Carina is the best thing for her, that she's happy and comfortable now because this is who she was supposed to be. In addition, I liked that Yosh being in a wheelchair wasn't the only defining trait about him, but it also wasn't shunted aside as though it didn't have any impact on his life.
I know some people were disappointed that the words asexual and aromantic weren't used on page in the book, but as someone on those spectrums, I'm totally okay with it. The author talks about it in a note at the end, saying that she couldn't figure out how to work into the story a scene of Hazel learning about and understanding the terms. I do think there were ways she could have done it, but at the same time, Hazel is only 13, and a 13-year-old not having crushes and not being curious about sex is totally fine and normal. It's not necessarily prescriptive -- yes, that 13-year-old might indeed turn out to be aro/ace but they also might just be a bit of a late bloomer, and that is completely fine. 13-year-olds shouldn't be actively thinking about having sex, anyway!
Very sweet and well-written, and now I want to live on a goat farm. But only if someone else milks them because gross.
