When Fairies Go Too Far




The fourth book in this hilarious chapter book series about an incorrigible underwear fairy, full of bright purple text and illustrations.

Has Oona Bramblegoop’s magical mayhem finally gone too far sideways?

Oona is thrilled to be a Fairy Council Member and her assignment is so much fun—making new rules for the fairy binder. She has tons of ideas! But her friends aren’t so sure these rules are needed, and then Oona finds out they’re causing a dangerous magical crisis.

She’ll have to find a way to stand up for what really matters if she wants to save her friendships and Blackberry Bog.

Packed with Fun Fairy Facts, humor, and lots of heart, this magical series celebrates finding friendship and your place in the world, even if you fit in a little sideways.

Praise for When Fairies Go Too Far

Praise for Oona Bramblegoop’s Sideways Magic: Newbie Fairy:

“There is humor for all ages . . . with delightful, burgundy-tone cartoon drawings. This is a fun chapter book for budding readers Sure to appeal to fans of the ‘Rainbow Magic Fairies’ series and ‘Unicorn Diaries.’”School Library Journal

Praise for Oona Bramblegoop’s Sideways Magic: A Boy in Fairy World:
“This second installment of Bramblegoopian misadventures is. . .set in a world that blends the quirky with the cute. Flowery, slug-speckled illustrations and footnotes with facts about the fairy world enhance the upbeat narrative and leave Oona poised to play detective in what promises to be an equally humorous third outing. . . Fun, funky, and imaginative.”Kirkus Reviews
