Spellfall

Natalie saw the first spell in the supermarket car park. She was wet and cold and had better things to do than pick up someone else's litter. But the trap had been baited by one who knew a lot more about spells than she did...
Snatched from her family and stranded in another world, can Natalie persuade her kidnapper's son Merlin to help her escape in time to save the enchanted land of Earthaven, where unicorns roam and giant trees provide sanctuary for her mother's soul?
Originally published by Chicken House/Scholastic in 2001, Spellfall was selected by American independent booksellers as the "book most likely to fill the Harry Potter void this fall".
"A thrilling and fast-paced fantasy adventure with shades of Tolkien and Pullman. Superb." The Bookseller.
