The tragic loss of her best friend, Josie Lee, leaves ten-year-old Seraphina questioning her destiny, until she learns she's the chosen one. Seraphina is whisked away by a frantic, talking butterfly on a quest to bring order back to a world inside a rainbow called Raiven with its six different, colored- realms by finding and returning a powerful rainbow crystal back to its wizard owner, which was stolen from an evil witch and her trolls. Raiven is a bridge between heaven and earth; Seraphina is motivated by the knowledge that she will get to see her best friend's dead spirit through magical fairies and their pixie dust. Seraphina will even meet and bond with a warrior fairy-boy and her own unicorn, which she unknowingly birthed through a wish on a shooting star. Throughout her journey, she passes a series of tests and discovers self-confidence and hope with the help of supernatural characters who guide her along the way. Most importantly, she learns that Josie Lee is more of a guardian angel to her than she realizes and has never really left her side after all. It doesn't even require magic, just faith.
