Jadie in Five Dimensions by author Dianne Salerni


Publication Date: October 5, 2021

Jadie Martin grew up believing she was abandoned by her parents as an infant. Creatures from the 4th dimension rescued her and placed her with a loving adoptive family. Now, Jadie acts as an agent for those beings, also known as Seers. She uses the 4th dimension as a short-cut means to travel anywhere on Earth, performing missions calculated to guide the world toward a brighter future.

But when Jadie breaks the rules to switch assignments with another agent, she accidentally discovers that her origin story is a lie. Doubting the Seers, Jadie starts asking herself: What are the true intentions of the Seers? Do her missions really make the world a better place? Most importantly, what will all-powerful four-dimensional beings do to a rebellious human girl when they realize she’s interfering with their plans?

A Wrinkle in Time meets Flatland in this thrilling, think-outside-the-box adventure that challenges the meaning of family, loyalty, and free will.



“A thrilling ride through a multidimensional universe and high-stakes action. Though the techno-speak is complex, the storyline is anchored by emotional themes of family, adoption, loyalty, and trust. Readers are invited to enter this imaginative world and consider the far-reaching possibilities.” ~ Kirkus

“A mind-bending, multidimensional adventure that also takes a deep dive into geometry and physics. Salerni offers a page-turning adventure tale and adeptly breaks down the math and science elements behind multidimensional theory for middle-grade readers. The book also has heart, touching on the emotional lives of two adopted 13-year-olds and the true meaning of family.” ~ Booklist

“A complex, engaging sci-fi adventure that offers a different perspective on our world, literally from a dimension beyond.” ~ School Library Journal

“Though mostly a fast-paced journey between worlds, it ultimately comes back to the themes of adoption, family, loyalty, trust, and love. Jadie and her family join together to come out on top and defeat the beings who are manipulating everything they do. Perfect for math and science fans who love adventure stories spanning across multidimensional world.” ~ School Library Connection

“Salerni threads a healthy dose of theoretical physics through the plot line, which should please young sci-fi fans. Well-earned reversals in the developing action will keep less mathematically minded readers engaged, while refreshingly un-clichéd characterization steers the narrative clear of tired tropes. While many middle-grade novels ask “What if…?” Jadie’s adventures give the question real teeth.” ~ The Horn Book
