Daisy Meredith is the new girl at the spiffy Grangewood School for Girls – and the first girl from a poor background to win a scholarship to one of the most famous boarding schools in England.

She dreams of midnight feasts, learning to play hockey and making new friends with the jolly rich girls. But not everyone wants to be Daisy’s friend – Sybil and Monica aren’t too keen for such riff-raff to join their prestigious educational establishment.

Lines are drawn, enemies are made and soon Daisy is on an adventure to disprove false accusations, search for the hidden treasure that is rumoured to exist, and discover who the mysterious man is seen wondering the grounds.
