The Light Princess [EPUB ebook] 

The Light Princess is a Scottish fairy tale by George Mac Donald. It was published in 1864. Drawing on inspiration from Sleeping Beauty, it tells the story of a princess afflicted by a constant weightlessness, unable to get her feet on the ground, both literally and metaphorically, until she finds a love that brings her down to earth. An animated version was released in 1978. In 2013, a musical version by Tori Amos and Samuel Adamson inspired by the original story was premiered for the Royal National Theatre in London. The stage production featured actress Rosalie Craig as the titular character. The musical was generally well-received, enjoyed an extended run in the theatre and will see its cast recording released in 2015.
