“There’s magic,” said Granny, “and then again, there’s magic. The important thing, my girl, is to know what magic is for and what it isn’t for. And you can take it from me, it was never intended for lighting fires, you can be absolutely certain of that. If the Creator had meant us to use magic for lighting fires, then he wouldn’t have given us—er, matches.”

She prided herself on her unrivalled knowledge of the properties of Ramtops herbage—none knew better than she the many uses of Earwort, Maiden’s Wish and Love-Lies-Oozing—but there were times when she had to resort to her small stock of jealously traded and carefully hoarded medicines from Forn Parts (which as far as she was concerned was anywhere further than a day’s journey) to achieve the desired effect.

She shredded some dry red leaves into a mug, topped it up with honey and hot water from the kettle, and pushed it into Esk’s hands.

Esk drummed her heels on the chair legs and sipped the drink. It had a strange, peppery taste. She wondered what it was. She’d tasted Granny’s brews before, of course, with a greater or lesser amount of honey in them depending on whether she thought you were making too much of a fuss, and Esk knew that she was famous throughout the mountains for special potions for illnesses that her mother—and some young women too, once in a while -just hinted at with raised eyebrows and lowered voices ….
