Oona loves being the Underwear Fairy, which means she gets to distribute magical safety undies to keep human children from falling down and hurting themselves. But when she gets trapped in the human world by Marco, a boy who wants to take a photo of her to prove fairies are real, she's horrified--don't let humans see you is one of fairydom's most important rules

Luckily, her cousin Horace and best friend Lucy (also known as the Tooth Fairy) help her get free. But then things get even more disastrous--Marco follows them back up to Blackberry Bog

Can Oona and her friends get Marco safely back to the human world before he does too much damage--and before the Fairy Council finds out?

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.
