How about a group of Musically Leaning Wonder Ride Books based upon Songs that have stories attached to them (or at least linked to stories like Opera or Ballet)?
God Beast: Based upon Stravinsky's The Firebird Suite
Animal: Based upon the Mouse King from Pyotr Ilyich Tchaikovsky's The Nutcracker Suite
Story: Based upon Wolfgang Amadeus Mozart's The Magic Flute (Die Zauberflöte)
Heck, just a group based upon the Nutcracker Suite could work well. The Sugar Plum Fairies as the God Beast Book, The Mouse King as the Animal Book, and the Nutcracker as the Story Book
