Some stories are about friendship. Some are about mysteries. Some are about cake.
This one is about all three. It's the start of a new term at the School of the Good Sisters and Hanna, Edie and Calla are ready to enjoy everything their extraordinary school has to offer.
But they soon realise that Something Is Most Definitely Up when their beloved Headmistress Good Sister June disappears - and nobody knows where she's gone. It's time for Hana and her friends to set out on an adventure to bring Good Sister June home. As they travel across the country following a trail of clues, they will learn about the power of family, friendship, and a well-timed slice of Victoria Sponge.
