About Ollie in Between

As endearing as it is humorous, this debut middle grade novel by Jess Callans is a tender, queer coming of age story about the courage it takes to find your own voice and choosing to just be.

Puberty, AKA the ultimate biological predator, is driving a wedge between soon-to-be 13-year-old Ollie Thompson and their lifelong friends.

Too much of a girl for their neighborhood hockey team, but not girly enough for their boy-crazed BFF, Ollie doesn’t know where they fit. And their usual ability to camouflage? Woefully disrupted.

When a school project asks them to write an essay on what it means to be a woman (if anyone’s got an answer, that’d be great), and one of their new friends is the target of bullying, Ollie is caught between the safety of fleeing from their own differences or confronting the risks of fighting to take their own path forward.

My Review

Okay, wow. This book. The authenticity of the voice. The raw, aching tenderness with which Callans tells this story. I’m tearing up even reflecting back on the book.

As I read the story, it felt very focused and very linear. It’s easy to follow. Ollie speaks directly to the reader sometimes, which I found endearing. Like, we’re in this together. I loved that.

Upon reflection, though, so much happens in the 244 pages of this book. Ollie grieves over their mom and unborn baby brother, whose deaths resulted from a pregnancy complication. Ollie and their sister, Lila, talk about PCOS (polycystic ovary syndrome) which runs in the family, and which Ollie may have.

They experience changes in friendships that seem common to middle school years. When their best friends sense pressure to assimilate into other friend groups to avoid being considered weird, they leave Ollie behind. The loneliness and confusion Ollie feels are so authentic. I felt like I was re-experiencing those moments myself. I couldn’t have expressed it nearly so well as Callans does.

Additionally, Ollie wrestles with questions about what it means to transition from girlhood into womanhood. While the people they interview often contribute thought-provoking or poignant answers, they never explicitly answer the unspoken question Ollie is really asking. Only through continuing to ask questions and explore what resonates authentically with Ollie do the answers begin to be apparent.

I also love the way that Ollie’s dad and sister respond to them. It’s not perfect. They make mistakes along the way, which stinks, but also felt so relatable. Oof. I know I’ve been there.

I think fans of books by Alex Gino and Nicole Melleby need to read this one. Ollie in Between also reminded me of Just Lizzie by Karen Wilfrid, another fabulous queer middle grade debut.

Content Notes

Recommended for Ages 8 to 12.

Profanity/Crude Language Content
References to the F-slur. (The full word does not appear on the page.) Bullying/homophobic/transphobic words do appear. Other characters condemn those words (though not always out loud).

Romance/Sexual Content
References to dating and kissing. Some discussion about puberty (breasts growing, periods beginning) and what it means to be a woman.

Spiritual Content
Ollie’s mom’s Iranian family stopped speaking to her when she married a white man in the US and had their first child baptized in a Christian church.

Violent Content
Reference to the death of a parent. Some instances of bullying (see above) and homophobic/transphobic behavior. Sometimes, this is perpetrated by people who may be well-intentioned and simply aren’t leaving room for people who don’t fit a gender binary. At other times, it’s clear that people mean to cause harm. Often, those harmful words are challenged or condemned.

Drug Content
None.
