For fans of Book Scavenger, a smart and funny math camp middle-grade mystery with built-in logic puzzles that readers can solve

Twelve-year-old painter Esther can't wait to attend Camp Vermeer, the most prestigious art camp around. But when her stepdad accidentally drives up the wrong mountain, she lands at Camp Archimedes -- a math camp! Determined to prove herself to the other campers, she tackles a brain-teaser that's supposed to be impossible, and solves it in a single day. But not everyone is happy about it... someone wants her out of camp at any cost, and starts leaving cryptic, threatening notes all over the grounds. Esther doesn't know who to trust. Will she solve this riddle before it's too late?

Featuring tricky logic puzzles readers can solve along with the characters and starring a unique, smart, and crafty young heroine, this story has just the right mix of mystery, humor, wit, and heart.

Review

“The isolated setting provides the perfect backdrop for this fast-paced mystery by Van Dolzer starring a quirky crew of well-drawn characters... Esther's leadership skills and tenacity are inspiring.” ―Publishers Weekly

“A good middle school mystery that includes, art, literature, logic, and multiple subplots…. Compares well to Chasing Vermeer and The Westing Game.” ―School Library Connection

“Esther herself is solid and earnest, the math aspect is engaging, and the exuberant energy of the story is contagious.” ―Kirkus Reviews

“[The story is] a lot of fun as readers participate in Esther's journey and solve puzzles alongside her . . . The ending successfully twists readers' expectations, and those who like thought puzzles will enjoy this book.” ―BCCB

“Genuinely sweet...readers looking for realistic middle-grade fiction will find David a likable guide.” ―School Library Journal on Don't Vote For Me

“Clever and witty.... not only fun to read but also easily relatable.” ―Deseret News on Don't Vote For Me

“Thoughtful.” ―Publishers Weekly on The Sound of Life and Everything

5.0 out of 5 stars A great mystery set at a fun location--math camp!

I've read all of Krista Van Dolzer's books, and I was excited that THE MULTIPLYING MYSTERIES OF MOUNT TEN pulled in Esther, a character first seen in one of her earlier books, DON'T VOTE FOR ME. She's spunky and dedicated to her art, so when she ends up at math camp instead, she's not pleased, and yet she rolls with it.

I love all of the math problems within the story and how they're mixed into the mystery. It's perfect for a middle grade audience, with just the right amount of wonder. Also, have you seen the cover for this book? It's amazingly detailed and fits so well with the book itself.

Finally, each of the supporting characters is fun and adds to the overall story. This is just another great book from Krista Van Dolzer, and I highly recommend it.

3.0 out of 5 stars A Math Mystery That Will Leave You With Questions
Reviewed in the United States on July 14, 2019
The Multiplying Mysteries of Mount Ten was written by Krista Van Dolzer. This book is a middle grade fictional novel set in modern times.
Summary: Twelve year old Esther can’t wait to attend art camp at Mount Veneer. She’s been dreaming about it for months. But a freak storm, and windy mountain roads lead to an unexpected detour, and instead, Esther ends up at math camp.
Soon Esther finds herself deep in a math mystery she is determined to solve. Will she be able to figure it out, and will she ever make it to art camp?
My Thoughts: I think that a middle school reader might enjoy this book. There is a very interesting premise, and I think a younger reader would enjoy trying to solve the mystery along with Esther.
However, I do not believe this book is one someone older would completely enjoy, and here is why-this book leaves many unanswered questions that never get explained or resolved. As an adult, that makes it difficult to say I enjoyed reading it, because I was left wondering what actually happened in several parts of the book (I don’t want to go into too much detail on the loose ends here, as it would ruin the story if you chose to read it.)
So, I would say if the middle schooler is one who just enjoys surface reads and likes helping solve a mystery, they are going to probably enjoy this read. If the reader is one who really likes to dig into a story, and wants all the loose ends tied up at the end of the story, they might find themselves a bit frustrated with this book.
Also, I have to say I found Esther to be quite rude and self-centered. I actually began feeling sorry for the other characters in the book, because she was always treating them so poorly.
It is kind of a shame too, because I could really see the potential with the creative theme to this story line, but it just came up short for me.
I would like to thank Bloomsbury Children’s Books for providing me with a digital copy of this book in exchange for my honest review. Thank you.

You can tell this was written by someone who loves math, and she's also an excellent writer. I enjoyed reading the book, and so did my kids. Highly recommended.

1.0 out of 5 stars Characters unlikable

I hate giving this book only 1 star. My kids (ages 13, 11, 8, and 6) and I were really excited about the premise of this story, a mix-up landing an artsy girl at math camp, finding and solving mysteries there...It sounded great. But as we got into the book we just could not enjoy it as the characters were unlikable and acted/thought illogically. The main character was especially unlikable as she constantly jumped to conclusions, assumed the worst of people, judged them by their looks and the fact that they were at math camp. It was just a real disappointment.

5.0 out of 5 stars Very fun story!
Reviewed in the United States on April 10, 2019
On their way to art camp, Esther and her step-father get stranded at a summer camp in the mountains. Drenched and soggy with more rain in the forecast, they have no option but to stay... at least for a little while. Judging the camp negatively since it's a "math" camp, Esther never dreamed what adventure awaited her. Within 24 hours, Esther solves the "unsolvable" puzzle and finds herself drawn into the mystery that begins to unfold around her. A missing camper, mysterious clues written about mythological creatures, and a good gang of math nerds to hang out with make for a great week at camp.

The book is written in first person, and in my opinion, the stylistic choices help to make the The Multiplying Mysteries and Mount Ten a very unique and interesting book. It feels a little like I was being told a story by a young friend. Though the writing style and the plot, I was drawn into the story and hurriedly turned the pages to see what would happen next. Even as an adult, I found the story to be engaging and enjoyable, and I think my students will feel the same way.

From a teacher's perspective, The Multiplying Mysteries of Mount Ten is a great book. First, it is entertaining and humorous. Middle grade students will enjoy the mystery and the relationships between the characters. The plot is entertaining even when the characters get carried away by their imaginations. Second, it is a smart book. The references to artists, works of art, mathematical terms, and mythological creatures give students a chance to re-encounter these words in context. The main characters solve ciphers and logic puzzles; the author even explains them in a clear and simple way so that the reader can learn how to solve them on his or her own. Third, the characters have high relational aptitude. Though there are some interpersonal conflicts in the book, the kids are able to work them out and develop meaningful friendships along the way. They model healthy behaviors, mostly, for the middle-grade readers.

I received a copy of this book for free from Bloomsbury USA Children's Books through NetGalley. The opinions contained above are completely my own.

While I found this book a little slow, I think students would like the mystery behind it. This book would be best in grade 5 and up.
