The First Tale from the Five Kingdoms

An exuberant, hilarious and wildly entertaining fairy tale with a cast of characters who are good, bad and very, very ugly.All is not well in the crumbling castle high above the mountain village of Fracture. The sorceress Lady Lamorna has her heart set on a new robe. A very expensive new robe. To get the cash she will stop at nothing, including kidnapping, blackmail and more than a little black magic. But she reckons without the heroic Gracie Gillypot, not to mention a gallant if rather scruffy prince, two chatty bats, the wickedest stepsister ever, a troll with a grudge – and some very Ancient crones.
