From the back of the book:
To some, the hedge wizard might seem to be a poor substitute for the wizard or sorcerer. Not as flashy as the latter, nor as recognised as the former. This is, however, a dangerous misconception. The hedge wizard is a rural, backwoods magician who relies as much on the superstition of his neighbours as on actual magic to make a living. He specialises in the use of cantrips; the minor incantations and simple spells that are largely ignored by most wizards and sorcerers.
