The Bag of Bones: The Second Tale from the Five Kingdoms (Tales from the Five Kingdoms)

Truda Hangnail is a very wicked witch, banned from the Five Kingdoms because of her use of deep magic. Then she comes up with a fiendish plan to restore evil to the Five Kingdoms, transforming the good witches of Waddingburn into shrivelled, wicked old witches who will help her take over King Frank's kingdom on his fiftieth birthday. Luckily, a sweet-natured half-human, half-elf named Loobly is witness to Truda's evil spell and sets off to fetch help. As the birthday party looms and Truda's evil gathers strength, Loobly enlists the help of Prince Marcus of Gorebreath and Gracie Gillypot, as well as old friends Gubble the troll and Marlon and Alf the bats, to stop Truda and send her packing to the house of the Ancient Crones to face her just deserts.
