About the Holiday
There may be no more beloved magical creature than the unicorn. Unicorns have been part of legend since ancient times, undergoing changes from an image of fierceness and power to a representation of strength and true love to today’s more glittery superstar. To celebrate today, learn more about the history of these mystical animals and check out the latest addition to the wildly popular unicorn-tastic Unicorn Diaries series!
Thank you to Scholastic for sharing a copy of The Secret of the Lost Gold with me.
The Secret of the Lost Gold (Unicorn Diaries #11)
By Rebecca Elliott
As the latest story in the Unicorn Diaries begin, Rainbow Tinseltail (Bo, for short) reveals that dark clouds and lightening foretell a storm, and over night winds, rain, and unipod-shaking thunder do sweep through Sparklegrove Forest, where the unicorns, gnomes, and other magical creatures live. In the morning, everyone wakes to find “a very big mess all across the forest.” It’s then that Mr. Rumptwinkle, the unicorn’s teacher at the Sparklegrove School for Unicorns (S.S.U.), cancels class for the day, instead sending his students out into the forest to see who needs help.

They find that no one—from the fairies to the gnomes to the mermaids, dragons, and trolls—has escaped the storm unscathed. “But the great news was that no one was hurt.” The unicorns bring some friends home for hot tea and buttermoon biscuits as they all talk about how they can help rebuild. Edna Gnome remembers an “old Rebuild and Repair spell” from “long ago” that could restore the entire forest at once, but she needs “special ancient gold nuggets” to make it work.
The next day, the unicorns head out for Queen Juniper’s castle to learn where to get the ancient gold only to discover that the castle has been damaged too. From Princess Greta, the unicorns learn that the gold has always been stored in a cave in the Dark Woods and is protected by a griffin named Edgar and from their werewolf friend Barry, they discover where the cave is: in the most dangerous part of the Dark Woods.

Undaunted (well, maybe a little) and brave, the unicorns continue their quest. Along the way they use their individual powers to outsmart a giant, calm upset night sprites, and cheer up “grumpy talking trees.” When they got to the cave, the unicorns were even able to befriend the griffin and retrieve the gold they needed.
Back at Queen Juniper’s castle, Edna makes the magic rainbow-colored dust and, as Bo writes, “Everyone worked together to rebuild our forest.” Queen Juniper held a royal ball with “scrumptious food, lots of desserts, and golden glitter fireworks” to celebrate. She even honored Edgar with a “majestic golden necklace as a special thank-you for protecting the forest’s gold.” And the unicorns? They earned their Treasure Hunt patches and made a new friend in Edgar!

It’s easy to see why Rebecca Elliot’s Unicorn Diaries is so beloved by early and newly independent readers. Each book in the series is warm and welcoming, beginning with its first chapter, which introduces new readers to the unicorns and world of Sparklegrove Forest with an illustrated map; a fun-facts description of the book’s new featured magical being (the griffin, in this book); surprising details about unicorns (for instance, that their horn is perfect for carrying cotton candy and can be used as a flashlight and that a swish of their tail enacts their secret power); and information about their school.
The Secret of the Lost Gold, the 11th book in the series, is a perfect addition to Elliot’s unicorn lore. Full of imagination; friendship; high-stakes, yet solvable challenges; magic; and humor, the story will captivate readers with its positivity, gentle suspense, and underlying message that they have the power to be brave and to take action to give back to their communities. The diary format of the book allows Elliot to combine larger-size, easy-to-read text with colorful illustrations that provide a natural, confidence-building bridge from picture books to text-only chapter books.
Whether your child is a fan of the Unicorn Diaries series or just discovering this magical world of reading, The Secret of the Lost Gold is a book you’ll want to add to your child’s home bookshelves. For classrooms, school, and public libraries, this latest trip to Sparklegrove Forest is a must.
