"Concepts are explained concisely and clearly, and a short glossary provides valuable vocabulary building. The slightly larger font makes the text inviting for emerging readers, and the illustrations blend perfectly into the story. Sassafras and the dragon prove to be able sidekicks in the vein of Disney characters...while this book is a natural fit for STEM collections, it deserves a place in all libraries serving young readers."
-- School Library Journal
"...the imaginative premise and the incorporation of STEM elements make this an attractive and engaging choice."
"...a delightful beginning reader. I will definitely recommend this to kids and I look forward to the other books in this series."
--Mel Barnes, University Bookstore
"Zoey and Sassafras are our heroes! My kids love unravelling their mysterious circumstance, and they even made their own "Thinking Goggles." Zoey is an awesome role model."
-- Megan Lingo, Reading Teacher at Chickadee Lit
