This was a great debut middle grade novel about a young neurodivergent twin girl who has dyslexia, dysgraphic and dyscalculia who is struggling to keep up in a new private school. She starts confessing her feelings anonymously online and finds she's not the only one at school who feels the pressure to perform or fit in.

Heartwarming, relatable and just filled with a memorable cast of characters. I especially enjoyed the sibling dynamic where each twin had their own feelings to work through. Highly recommended for fans of books like Figure it out Henri Weldon, The unlikely heroes club or Very bad at math.

Audiobook. 4.75 stars. I wish this could have been around when my kids were in elementary/middle school. Possible battle book. Learning differences.

Twins Ruby and Bryce are going to a new private school, Benton Academy. Ruby who thinks she is the dumb twin is worried she is going to fail out due to her recent dyslexia, dysgraphia, dyscalcula diagnosis and her difficulty passing her classes at school. Benton proves challenging for Ruby for many reasons, but mostly due to her anxiety about her learning differences and what that could mean for her brother's future at the school which he loves. When Ruby turns to an anonymous social media site embedded in the school, she learns that she is not the only one who feels a lot of pressure to succeed at Benton. Due to her supportive family, she confronts many challenges with aplomb. She and Bryce learn about eachother. And Ruby balances courage and fear along with all the things that make a perfect coming of age/middle school story that is completely elementary appropriate.

Authors are in Boulder.

Ruby is entering 6th grade and struggles with dyslexia, dysgraphia and dyscalculia. So when her twin gets into Benton Academy -a charter school for the ‘smart kids’ in the school district, she isn’t thrilled that she has to go too. Her parents want to stick to a schedule and have both at the same school. So Ruby has a 504 plan and gets accommodations, but it’s still a struggle and very stressful. Ruby posts her feelings on Chatterbox, anonymously and finds out that many Benton Academy kids share her feelings.

Ruby is beginning middle school that is a charter school with challenging academics. Not only is she leaving the friends she made while in elementary school, but she’s ashamed of her dyslexia and thinks of her twin brother as the smart one. Ruby learns to navigate these challenges and learns a lot about herself along the way. The book is a thoughtful exploration of what gifted means and the stress that parents and teachers unknowingly can put on their children and students. Ruby comes out on top with the help of her new friends and a few exceptional teachers.

Not allowed to rate this as I have my ARC only unofficially, but I really liked it!

[Carrie]

This is a really nuanced story about one girl dealing with dyslexia. Ruby considers her twin brother the “smart” twin and the reason they are attending a new private school.

[Molly]

LSuch a sweet story. I loved that the main character has dyslexia and how it was woven into the story.

Ruby is not excited to leave Lincoln Middle School, where her best friend Ella attends, and go to Benton Academy. Since her twin brother Bryce is excited about the academic enrichment available at the charter school, and her parents don't have time to take the children to two different schools, she has agreed to go. Since Ruby has been diagnosed with dyslexia, dyscalculia, and diysgraphia, she has an extensive 504 plan and several accomodations. She worries about being in Mrs. Taylor's language arts class when the teacher asks what books people read over the summer; Ruby has only read graphic novels, which her 5th grade teacher didn't count. The class is assigned Oliver Twist to read. Ruby does make a friend in the quiet Thea, who seems to try to be as average as possible, but is glad when her father takes her and Bryce to the pool so she can hand out with Ella. Bryce's anxiety decreases at school, since he is able to make friends like Kennedy, who installs an electronic keypad on his locker and shares a lot of the same interests. There's a lot of homework, at least two hours a night, which is very hard for Ruby despite her accomodations. Her parents offer to get her a tutor, and even Bryce offers to help. When she is overwhelmed with the work, Ruby creates an account on the ChatterCube app, and as @confessionsofamango (based on a meme her mother has shown her about a line up of mangos and a love bird that looks almost like on of the fruits), posts that the school is expecting too much and should be more accepting of failure. She writes her tag on the announcement white board, and her post goes viral. There are lots of comments from other students who also feel pressured to succeed, especially by their parents. The principal gets upset when many parents complain, and threatens to punish whoever is posting. The kids at the school, however, start bringing mangoes in their lunches in solidarity! Thea admits to Ruby that she is struggling with the transition from Montessori classes to Benton, even though Ruby won't admit to anyone that she is the poster. Ruby does benefit a lot from a tutor who makes her see her difficulties in learning in a different way, but when the truth comes out, the mango really hits the blender. With help from her parents, Ruby is able to forge a new way forward for herself.
Strengths: Ruby has a great voice, and I loved that she wanted to try to change what she felt was a difficult situation. It was good to see her parents really trying to support her with tutoring, and they didn't seem to pressure either child with unrealistic expectations. Thea and Kennedy's parents were more problematic, so it was interesting to see a range of expectations. The social media aspect of this will appeal to middle grade readers, and the descriptions of accomodations, coping skills, and a really great tutor were good to see. This ends on a happy note, with Ruby setting up a Fruit Bowl support group.
Weaknesses: Would this have been different if Bryce had been enrolled in a school that was designed to meet Ruby's needs, but he complained about the lack of academic challenges? While there are good arguments for why Ruby was enrolled in the school, I felt bad that she struggled so much.
What I really think: This is a good choice for readers who liked Garcia and Williams' Mixed-Up, Hunt's Fish in a Tree, Davis' Figure It Out, Henri Weldon, or Dilloway's Five Thing About Ava Andrews.

*Thank you to Netgalley, Kate Lumsden, and the publisher for this advanced copy in exchange for an honest review.*

Wow!! What an important book for our kids today. This is the story of Ruby, who against her will is following her genius twin brother Bryce to a magnet school that is highly academic and challenging. Not only is she leaving her elementary school friends behind, but she knows, she KNOWS, that she does not belong at this school. Ruby has dyslexia, dysgraphia, and dyscalculia, and she is ultra aware of it. She also works very hard to make sure nobody else knows. When the pressures of this new school get to be too much, she has to vent. But with nobody to turn to, she makes a post on social media, and Ruby could not have foreseen the consequences of that action.

I will definitely be buying this book for my elementary school library and encouraging students and teachers to read it. Not only does it highlight characters with different abilities, but it also brings up the very important topic of outside pressure and the paralyzing fear of failing that a lot of kids have. Kids need to learn to fail with grace, and learn what to after that. Failure is inevitable, even for the kids that are seemingly good at everything. Thank you for bringing this important topic to light! I imagine some excellent conversations stemming from this book.

I read an Advanced Reader Copy of this book.

What a great read! I read this alongside my fifth grader. It was funny, engaging, and at times, profound. It sparked so many conversations between us about perfectionism, coping with failure, self doubts, feeling stupid, and the importance of being kind to others and oneself. And it was funny! So many great lines and moments that left us in stitches.

The story centers on Ruby Emmerson who's just starting a new school with her academically gifted twin brother. Ruby has dyslexia, dysgraphia, and dyscalculia, is failing math, and may soon be kicked out of their elite middle school. To cope, she starts posting anonymously on social media about feeling like a failure and not belonging at their school. To her surprise, this resonates with many of her classmates, and it starts a school wide movement. The school administration comes down hard on what they see as spreading discontent and gripes about the school and threatens to expel participating students. Through this process Ruby discovers more about herself, to not resent how her brain works, and to value and not fear failure. She discovers her own voice.

5 stars, highly recommend!

This was a great middle school read. Ruby has dyslexia and doesn’t feel like she fits in at her new advanced school. I like when she describes how she’s thinking and how her dyslexia affects her. It’s real and honest. She’s also honest about how she sees herself (as the dumb twin.) Ruby starts a secret social media account describing how she feels like she doesn’t fit in and others join her. I appreciated how the author incorporated a place for students to share their feelings about how overwhelmed they feel. I think it gives the story a realistic feel and brings up a very real topic of the pressures tweens face. I loved the character of Ruby’s tutor. He seemed very helpful and made her see herself in a different light. My favorite part of the book is when Ruby discovered that the tests she took actually prove that she is smart. It completely changes how she sees herself. I also liked how her parents stood by her side when Ruby made the very grown up decision to not remain anonymous on social media anymore.

[Madae]

Confessions of a Mango is a wonderful middle grade book. Ruby and Bryce are twins. They are starting the new school year at Benton Academy, a rigorous, academically challenging charter school. Ruby has dyslexia, dysgraphia and dyscalculia, which make school challenging. She feels like the dumb twin, while Bryce is academically gifted. After failing her first math test, Ruby creates an account online where she talks about feeling like a mango in a line of lovebirds. The mango may look similar in color and shape, but it's different. Ruby's account gets a lot of attention and Ruby realizes that she's not alone in feeling inadequate.

This was such a good book! I'd recommend it to students or use it as a read aloud for class. A lot of students feel "dumb" when school is challenging and Confessions of a Mango is a great story about how we all learn in different ways.

Thank you, NetGalley and Little, Brown Books for Young Readers, for the ARC.

[Jeni Enjaian]

Kate Lumsden did an excellent job telling Ruby's story. Ruby has always pictured herself as the dumb twin, especially after she receives her diagnoses of dyslexia, dysgraphia, and dyscalculia. When their parents enroll the twins in a new middle school, one designed especially for high performing students, Ruby dreads the move and also places immense pressure on herself to do well because she does not want to be the reason that her twin brother can no longer attend the school if the work proves too difficult for her. (Her parents cannot send the twins to separate schools due to logistical reasons.) While attending the school Ruby faces the challenges that she expects but also discovers that she's not alone in feeling like a mango, aka someone who does not fit in when the world expects them too. I really enjoyed this book.

[Renee ☔]

Cute book. Ruby, the "dumb twin", has all the dys's: dyscalculia, dysgraphia, dyslexia. When their parents enroll the twins into a special school that "challenges" students, Ruby feels the pains of her labels more acutely than ever. With the bar higher than ever, her low self-esteem envelops her. Meanwhile, her twin is soaring higher than ever for the first time in his life. Ruby and her twin brother make new friends, with each latching onto someone with whom they click but Ruby doesn't feel like she belongs. Ruby anonymously starts an online forum for "Mangos" - students at the academy who are struggling with all the pressures. Students quickly embrace this opportunity to vent and it's a hit with the student body. But not with the administration.

I won this book on Goodreads. I quite enjoyed it and as a retired special education teacher appreciate its addressing this label.

[Nicole M. Hewitt]

A funny and relatable story about dealing with the pressures of today's academic environment! I loved how it showed that every kid has strengths and weaknesses--Ruby has dyslexia and other challenges, but she's also a deep thinker and excels in logical reasoning and other ways. But she's always seen herself as inferior to her twin brother, who is more traditionally "smart" (as in, he does well in school--especially math, which is Ruby's worst subject). When Ruby anonymously talks about her feelings of inferiority and the pressure to excel online, she's shocked to learn that many of the kids at her school are feeling those pressures! And she starts to realize the value in being just who she is--strengths and weaknesses and all.

Funny, highly engaging, and whipsmart, this book will be a hit with middle grade readers!

[Ben Schrag]

I read an Advanced Reader Copy of this book.

I loved this book! I bonded with Ruby immediately and found her emotional arc compelling and engaging. Her story is also very well paced, making for a quick and effortless read. Seriously, it reads well. And I loved the book’s sweet and heartfelt message about bravery! Working in libraries I read a lot of middle grade fiction and I think middle grade readers and adults alike will greatly enjoy this book.

Confessions of a Mango by Kate Lumsden and Nate Pieplow is a story of twins who find their academic fates are entwined even though their academic skills are wildly disparate. The story brings up ideas relating to giftedness, neurodivergence, academic pressure, finding your voice, and a deft exploration of bravery vs. intelligence.

I thought this was a strong debut novel from a promising pair of authors. Whether you feel like a Mango or feel like a Lovebird, this book is for you!

[Tamsyn]

Veering towards 4.5 stars for the way this book approached the main character's trifecta of dyslexia, dysgraphia, and dyscalculia. When Ruby gets stuck going to a new school because it's a great fit for her twin brother and makes sense with their parents' schedule, she dreads it because she considers herself the dumb (but brave) twin. When she opens an account that points out the pressure she's feeling, she finds out that she's not the only one who might be feeling this in a variety of ways. But the administration does not appreciate the camaderie that develops, thinking this is negative pushback about the school. A lot is learned here, by Ruby, her parents, friends, and the school community at large. Excellent and engaging.

[Suzy]

This is such a good book. Ruby and Bryce are twins, but Ruby has always viewed herself as the dumb twin. Her brother and she are starting at a new school, but she's really not sure she belongs here. She has dyslexia and she has always seen that as bad and that she's not smart. But through this book we see how her dyslexia affects how she sees things differently. Not always bad though.
She might be struggling in school, but with the help of some friends, a tutor and her family she learns that maybe it isn't all bad after all.
Such a great story of figuring out who you are and where you fit in, in a new situation.

[LS Johnson]

It has to be hard to be a 2E student, and watch your twin sail through school so easily. That is what Ruby believes to be happening when her and Bryce begin attending Benton Academy. Ruby has dyslexia, dysgraphia, and dyscalculia and even with a tutor, struggles to pass. In a moment of frustration, Ruby anonymously posts, using a mango as her avatar, about her feelings and emotions. To her surprise, many other students from the school begin to post about their emotions as well. The story has a positive outcome. I appreciated the support Ruby receives from her parents. It was also good to watch Ruby come to understand that every student struggles with something, even her brother.

4/5 stars
Really enjoyed the audiobook. Explores dyslexia and other learning disorders as Ruby starts a new competitive school alongside her twin, Bryce. The book explores what it means to be "smart" and "gifted" as opposed to "dumb." The twins have a good relationship (which is refreshing and one of the best parts of this book) but still inevitably compare themselves to each other. Ruby, in fear of failure and frustration with the new school, posts on a social media site and it goes "viral" at the school as others begin to share their own frustrations. I found the social media portion of the story somewhat unbelievable, but its still a fun book that could make a good class read aloud.

[Jennybeast]

I like how much this centers Ruby and her ideas -- she makes a lot of her own decisions and learns a lot from them, and comes up with her own solutions when she sees a need and a way to help others. That's a pretty amazing storyline. I also love that her solutions all have to take other people into account and collaborate with them -- that's also great. The book is an easy read -- compelling characters, quick chapters, a quick moving plot -- it just sucks you into the story in all the good ways. I love that it's about learning to appreciate different brains, and learning to create your own space and expectations.

E-ARC provided by NetGalley. What a great story for middle grade readers! This would definitely serve as a great classroom read together for students so that those who identify with the stuggles and insecurities of being a "mango" can see themselves, and those who don't feel that way about school and their abilities can hopefully understand and empathize with their classmates, siblings, and friends. I love the reframing of ideas about being "smart" and the focus on being brave to let friends and parents know when you are having a hard time. 5 stars

[sparkypink]

Confessions of a Mango is a great story that shows kids that while they may think they are the only person struggling with the pressures of school, families, and friendship, all it takes is one brave person to speak their truth out loud so others won't have to feel they are alone.

I would recommend this book for upper elementary and middle school students. It could be an eye opening book for parents of children those ages, too, so that they can be reminded of what it feels like to be that age again.

I received a digital ARC thanks to NetGalley and the Publisher.

[Beth]

Thank you to Netgalley for the free arc! I enjoyed this story told through the eyes of Ruby, a middle schooler who has dyslexia, dysgraphia, and dyscalculia. The authors do a great job of explaining what these are, how they affect her, and strengths/weaknesses without being preachy. We really get to understand Ruby and how she is feeling. As a twice exceptional learner (being really intelligent and also having learning differences), hers is a voice that we don't often get to hear in YA literature.

[Karen]

Ruby is upset to have to go to a new middle school because it is easier for her parents’ schedule. When her twin brother is accepted at Benton Academy, it is just easier for her to attend too. Ruby has just learned about her dyslexia, dysgraphia, and dyscalculia diagnosis and feels especially over her head in the new school. To cope with her feelings she posts anonymously on social media and ends up going viral because many students share the same worries.

[Candace]

4.5 stars!! I wish this book existed when I was growing up. A great book about the struggles of children with learning disabilities and those without. This book is easy to read and shows so many sides of a child from school, struggles, parents and siblings. The parrot made it worth reading on its own!!

[Jgramley]

My twin brother was Bryce and I was to an extent Ruby growing up. I sat and did the SAT early because my brother did when he was trying to get admitted to a math and science academy. Being a twin is so rewarding and yet challenging too!
The reframing on dyslexia is so needed! I will definitely be getting this into the hands of my students!!!

[Nancycampbell]

Ruby Emmerson has always felt like she is dumb, because she has dyslexia and struggles with reading, writing, and math. When she and her twin brother start sixth grade at Benton Academy, an academically competitive charter school, Ruby fears she will fail. Confessions of a Mango handles both twice-exceptionality and giftedness with respect and compassion.

[Laurel Zeisler]

Great title and appealing cover art. I felt bad for Ruby at times, but I appreciate that the author wrote about these topics. Dyslexia is a tough struggle and there should be more books written about it. I would definitely recommend that this book is added to a school library's collection.

[Daniel Long]

I loved this book—one of the best mid-grade novels I’ve read in years. It’s heartfelt, wise, and often quite funny, with important messages about family, friendship, and self-acceptance. I strongly recommend this book to fans of mid-grade fiction. Ruby’s is a story you won’t soon forget.
