I just found LUNA by @AuthorRABishop and it has such a whimsical, fairytale quality to it! You may enjoy this one:
A harmonious civilisation of angels live on the colourful and idealistic planet Venus.
However, one wild and comical rebel does not fit into this picture. The spontaneous angel Luna, is regular gossip throughout the galaxy, due to her continuous need to break the universal laws. Finally Luna is served punishment and booted from heaven.
Arch Angel Michael has sent her on a quest, to find Professor Starling. With deliberate brain damage, she is held in a London hospital, until a suitable foster parent is found. With a dog as a friend, and her trusty foretelling scroll, Luna is lead to enrol into college to complete her mission.
Luna meets charming college teacher Professor Starling, an environmentalist, who wants London to evolve in an eco-friendly direction. Luna who has a duty of compassion for Earth harmonises with his ideas, and Starling finds himself falling madly in taboo love with his student.
Her scientific secret could make Starling’s dreams come true, and help Earth survive against climate change. But first, can Luna convince him she is really an Angel? Or will he hand her over to evil government men and let the doctor label her insane?
