The Star Cloak (Fairy Realm Series #7)

Every year the Realm has a great festival, called the Night of Wishes, when Queen Helena puts on the precious Star Cloak and by its magic is able to grant wishes. This year, though, there's a problem: it's the night before the festival, and Giff the elf has accidentally damaged the Cloak!

Jessie knows that to save the Night of Wishes, she must get the Star Cloak repaired by the night-dwelling star fairies of Stardust Mountain, the makers of the Cloak and the only ones who are able to fix it. She doesn't have much time — can she save the Realm's special night?
