“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

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.
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

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.

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.

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

Hazel lives on a farm with her two mothers and her older brother Rowan. They have a heard of goats that her Mom milks for her business of making soaps and other products, and Mimi is a lawyer in town. Because of a change in the train schedule, Hazel has to go to another middle school, leaving her friend Becca behind for 8th grade. Since a girl at her old school, Kristen, was always very mean, calling Hazel "goat girl" and making fun of her for crying, Hazel wants to make
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

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

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.
The first thing that I want to say is that I absolutely love how easily inclusive this book is. And that every book ever needs to follow in its footsteps.

This book doesn’t focus on the fact that there are people who are gay, black, Jewish, ace+aro, or in a wheelchair, they’re just people. And the fact that this exists so easily makes my heart so very, very happy.

Hazel’s Theory of Evolution was on my radar from the second I knew of its existence (early 2019, I believe), and I was so ready for ano

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

Hazel’s Theory of Evolution by Lisa Jenn Bigelow

Release date: 10/8/19

From the author of DRUM ROLL, PLEASE comes this quiet, character-driven, middle-grade novel overflowing with heart and raw emotion.

Introverted eighth-grader, Hazel, lives a peaceful life on a goat farm with her animal books, two moms, and her older brother. Her life takes an unwelcome turn when the school districts are redrawn and s
Okay. I looked at the cover, read the summary, and now I’m officially addicted.
I'm sad I didn't enjoy this more.

It was mostly because I found Hazel irritating, even though that's just me (maybe because she had too much in common with the parts of middle school me I wish I could forget). However, she is a realistic middle schooler with her jealousies and stubbornness and close-mindedness, and she's dealing with a lot! Her anxiety isn't helping things.

However, it's middle grade with an aro-ace POV (!!) with other queer characters and so much other rep besides, and it treats

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

I absolutely loved Hazel! I laughed out loud and then cried in the same chapter. I could not put it down. As an adult reading I remembered the awful awkwardness of middle school. I moved to a new school in 7th grade and I totally agree with Hazel, it sucked! You will fall in love with her new friends and want to reach into the book and give them hugs. And now I REALLY want to get a goat. And I’m naming my next pet Arby.

This would be a wonderful read for tween or adult book clubs.

Good for middle school but the character, while in 8th grade, read younger.

I did not realize how much I wanted aroace rep in middle grade. Instantly recognizable characterization that has me clamoring for more characters like Hazel.

So many themes woven into this book. Bigelow gets the tone of the young people spot on. (I have this on the authority of my 12 and 14 year old granddaughters.) Well done weaving through difficult times!

Y'all I'm in tears right now. In a lot of ways, Hazel's asexuality and aromanticism were such a small part of this book but god I wish I had this rep as a kid. I wish I had someone like Mimi who could recognize what I was(n't) feeling and tell me "There are so many good ways to be in this world." I love that even if Hazel doesn't fully get it yet, Mimi is still determined not to let it go unsaid because she'll get it eventually. And she'll remember that conversation and know her mom supports he ...more

I absolutely LOVED this book. Early on I saw things that just called out to me, but what makes me know that it was a special book is that I didn't want it to end. I wanted to stay with these characters for longer. There are going to be some that complain about the way the LGBTQ+ community is so casually represented, but that is almost what makes it better.

Ugh! Do you remember the uncertainty and anxiety of middle school? Remember analyzing everything you said, everything others have said to you? Hazel's Theory of Evolution brought me right back to that time of constant self-doubt, and as uncomfortable as it was, I loved it.

(Full disclosure, the author is a friend of mine.)

I loved this book! Everything that Lisa writes is heartfelt and tells a a beautiful story.

I found this story emotionally harder than the other ones, but that is probably entirely due to the fact that it resonated with my fears about raising kids and what they might have to deal with as pre-teens/teenagers that I won't be able to (and shouldn't) protect them from.

Wow! Lisa Jenn Bigelow has written a gem of a story. In Hazel’s Theory of Evolution, we meet a timid 14-year-old who thinks her best option for dealing with a district move to a new school for 8th grade includes hibernating. What better way to get through a stressful year without best friend, Becca! Meet Carina and Yosh! To complicate matters, one of Hazel’s two moms is pre
What a fantastic read!

Due to a school rezoning, Hazel must complete her 8th grade year at a different middle school. This means that she and her best friend, Becca, will no longer be together throughout the week. Hazel has decided that she will keep her head down and just get through the school year.

But things don't always go as planned.

I struggled with this book initially because I had not remembered it was a middle grade novel when I was rushing through my TBR to find my next read. It took me a while to adjust to the reading level and I do think, objectively, the story and characters took a while to build and were not as compelling at the start. I imagine that I stuck this book on my TBR because it's about a girl being raised by two moms. I find myself super hungry for anything at all that might give me insight into how my da ...more
