A girl from the forest arrives in a bustling kingdom with no name and no idea why she is there, only to find herself at the centre of a world at war. She enlists at Pennyroyal Academy, where princesses and knights are trained to battle the two great menaces of the day: witches and dragons. There, given the name "Evie," she must endure a harsh training regimen under the steel glare of her Fairy Drillsergeant, while also navigating an entirely new world of friends and enemies. And with the witch forces moving nearer, she discovers that the war between princesses and witches is much more personal than she could ever have imagined. Set in Grimm's fairytale world, Pennyroyal Academy masterfully combines adventure, humour, and magical mischief.
