“Just because you don’t understand it doesn’t make it illogical.”

Hazel knows all about life on Earth. She could tell you anything from what earthworms eat to how fast a turkey can run. That’s because when she’s not hanging out with her best friend, Becca, or helping care for the goats on her family’s farm, she loves reading through dusty old encyclopedias. But even Hazel d

October Rose Definitely! This book has lots of great messages and representation that a 13-year-old girl could really enjoy and/or benefit from.

There's one section towards the end, where Mimi's talking to Hazel, and it's everything I wish I'd been told when I was Hazel's age, that it's okay not to want a romantic relationship or a sexual relationship, that all the stupid heteronormative milestones and relationship expectations aren't actually requirements and it's okay to want something else, or only parts of them. ...more

This book was very different from what I expected, but it was also very good. It's mainly about one of Hazel's mums being pregnant again after two miscarriages, and Hazel having a hard time dealing with her anxiety surrounding this pregnancy. At the same time, Hazel is starting at a new school and feels her best friend drift away from her when she becomes friends with Hazel's former bully. She learns that there's always room for hope in any situation, and that you can always make room for new fr ...more

Thank you to Harper Collins & HarperKids for sending me a finished copy in exchange for an honest review and promotion. All opinions are my own.

Can we please have more middle grade contemps like this!? To see a middle grade book like this that's just so inclusive makes me cry for middle school me who didn't have anything like this. I'm so happy future generations will.

This book centers on young Hazel who has been moved to a new school thanks to new districting guidelines. While at this new sch

For the majority of this book I was feeling like this was a 3 or 3.5 star read. There definitely wasn’t anything wrong with it, but I also wasn’t totally engrossed by the story. Hazel has to move to a different school and ends up drifting away from her only friend while also dealing with the stress of one of her moms being pregnant. But damn, those last 50 pages just hit me in a way I wasn’t expecting and had me SOBBING.

I liked how casually queer this Middle Grade book was. Hazel has two moms a

Thank you to the author and HarperCollins for an ARC of this book.

Can I just say that I consider Lisa Jenn Bigelow one of the most underrated middle grade writers whose books I've had the pleasure to read? Last year, her book DRUM ROLL, PLEASE was one of my favorite reads of the year, and now HAZEL'S THEORY OF EVOLUTION has also captured my heart. I sincerely hope you'll add this book to your TBR list to when it's released on October 8th.

4.0⭐️ “There are so many good ways to be in this world.”

This beautiful message encapsulates a lot of what this book is all about. I haven’t read a Middle Grade novel that offers representation in so many ways, without it seeming at all effort full or done to check boxes. This is a book that will give many young readers a feeling of being seen in literature, perhaps for the first time, and that is so important. I hope teachers, librarians and booksellers find ways to get it into the hands of kids

Honestly this might be the best book I've ever read, and I'm not even the intended audience.

The book follows 13 year old Hazel who is starting her 8th grade year at a new school, thanks to district rezoning. Hazel is 13, with frizzy hair, glasses and lives on a farm in Michigan and to be honest I was pretty sure this was my literal exact childhood. Introverted, loves to read and spend time outside? The biggest difference is that my farm had Pumpkins instead of goats haha.

Anyway, This is a part

You know what? This book was way more EVERYTHING than I expected. I realize it is classified as middle grade literature, but I would say it’s intended for older middle graders as well as the YA crowd. There’s just a little language (ex: damn) and some younger kids may be all giggly in a class read aloud where the word “teets” keeps being mentioned (because they live on a goat farm where goats are milked regularly). One of Hazel’s moms has experiences two miscarriages and so there’s a lot of fear ...more

Aro-ace main character who has 2 mothers, disabled kid rep and trans kid rep, and just for this, it deserves all the stars.

I've never read something so heavily focused on miscarriages, and the impact it had not only on the parents, but on the siblings as well, and while it can be a difficult topic, I found it well done.

Even though the terms are and ace aren't used in the book, the signs were here. I was able to see them because I'm familiar with them, but the author's note at the end was very w

This was so wonderful for so many reasons. Any books about the struggles of being in middle school—friends, fitting in, deciding what you’re now too old for and what you’re still too young for—will always have a special place in my heart.

Well this was a delight.

Hazel is the sweetest 14 year old you'll ever read about. She loves her science books, her animals, her friends and her family so much my heart explodes just thinking about it. She's full of wonder, cheerfulness but also feeling like the odd one out.
Her relationships with new friends, old friends, her family and her animals were all so realistic and imperfect but beautiful.
And of course, she spends a lot of time questioning the meaning of love, with regards to friends and

This book is a delightfully queer middle grade novel about a relatable and sweet feminine protagonist, with some neurodivergent qualities. I will handsell this, and particularly recommend it for classrooms.

When Hazel is forced to start at a new school due to redistricting, she plans to lay low so as not to become "Goat Girl" - the mean nickname from her old school. She tries to hold onto her old best friend Becca, but Becca's suddenly interested in cheerleading, and she isn't sure about her two new friends, so when one of her moms tells her that she's pregnant, Hazel feels like she can't tell anyone. Her mom has had two miscarriages before and Hazel worries that this pregnancy will turn out the sa ...more

Even though I enjoyed my time reading it and enjoyed the way that the author introduced and handled certain topics and situations (as abortions, discovering your own sexuality, acceptance to who you are and acceptance and love towards queer people), I must say that overall I found this book to be quite... okay.

Nothing special and nothing new to add to the whole book community.

This was so sweet! There is a lot going on here, so the ace/aro stuff is done with an extremely light touch, almost blink-and-you-miss-it. But overall this exploration of family, grief, love, and identity is really lovely.

This is one of the most heartwarming middle grade books I've ever read.

Hazel has a lot going on: keeping up with the family farm, surviving the eighth grade at a new school because of redistricting, and now to top it off: one of her moms is pregnant again after having two miscarriages. Navigating the next few months will be more challenging than milking the goats on her farm, but Hazel will learn about herself along the way and form new relationships.

This coming of age story is perfect for new

I read this book while trying to overcome a reading slump and it couldn't have come in a better time. Despite being a middle grade book it touched on a lot of really powerful and important subjects, and also I don't think I have ever read a book with so much representativeness, and one that comes fluidly and you can tell is not because the author wanted to reach a quota. The characters feel like real people, and their struggles are also real.

Hazel is a little odd, especially by rural Michigan standards. She has two moms one of whom is black and the other of whom makes soap out of organic herbs and goat milk from their own farm. Hazel's always liked animals better than people. The only thing standing between her and the mean popular girls who call her Goat Girl is her best friend Becca.

So when the school district rezones her into a new middle school, Hazel is dreading 8th grade. And at first her forebodings seem justified. One of he
