When the worst hurricane for centuries sweeps through the British Isles, a 200-year-old giant beech tree in a country park in the county of Limerick in Ireland comes crashing to the ground, making Spriggy, a mischievous tree-sprite, homeless. Spriggy takes up residence in Gilly's head, and under the guidance of the wizard Merlin, Master of Space and Time, the tree-sprite takes Gilly and her brothers Sam and Jonathan on many adventures of the mind. Under the Merlin Spell is the prequel to Margaret Mann's much loved The Merlin Set-Up. It will be enjoyed by all who have followed Sam, Gilly, Tom and Lucy through their other adventures, and by everyone who loves a good story. Written with humour and insight, this book will be an inspiration to all who yearn for a better world.
