A nightmarish danger threatens from the other side of reality...

Armed with only a frying pan and her common sense, young witch-to-be Tiffany
Aching must defend her home against the monsters of Fairyland. Luckily she
has some very unusual help: the local Nac Mac Feegle - aka the Wee Free Men
- a clan of fierce, sheep-stealing, sword-wielding, six-inch-high blue men.

Together they must face headless horsemen, ferocious grimhounds, terrifying
dreams come true, and ultimately the sinister Queen of the Elves herself...
