The Night Fairy by Laura Amy Schlitz
The Night Fairy is about a fairy named Flory whose wings get chewed up by a bat. Now flightless and terrified of bats, she decides to try a different lifestyle. She becomes a day fairy. She lives in a birdhouse, befriends a squirrel, and dresses in flower petals. Even the daytime isn’t always so easy for a young fairy, though, and this is the story of her struggles to survive, to recover, and to make her greatest wish come true.
The language of The Night Fairy is sometimes so plain that it take some of the enchantment out of the tale. But overall, I think it’s an enjoyable story for young readers (I’d guess around 7-8 years old).
