Dragon's Green

Effie Truelove has made a promise to keep her grandfather's magical books safe from danger.
Whatever it takes.
But it's not always easy when you're a pupil at the Tusitala School for the Gifted, Troubled and Strange.
Together with her new schoolfriends Effie must travel to the mysterious Otherworld and brave the terrifying Diberi, a secret organisation with plans that could destroy the entire universe.
