Be*Tween is a hot and popular band on Earth. They were originally scheduled to play at a beneficial concert for Ravenswood, but for some reason they disappeared, and hot teen singing star Johnny Conrad (really the Skultum in disguise) came to Ravenswood in their place in Spellsinger.
While going to Aldenmor in Trial by Fire, Kara and Lyra are separated from their friends, ending up in a place between realms. They come upon a fairy rave where Be*Tween was performing, revealing themselves to be real fairies. They are:
- Sylina, a siren: lead singer
- Crimson, a pixie: high-energy drummer
- Andiluna ("Andi"), a sprite: guitarist
Their song "Supernatural High" is Kara's favorite.
-  "Supernatural High"
-  "Spirit of Avalon"
-  "Feel the Magic"
-  "Friend in You"
-  "Golden"
Three of their songs first appeared in Princess Gwenevere and the Jewel Riders.
