From the Publisher:
The witch is a "naturalist" spellcaster who casts arcane spells using time-honored hearth wisdom rather than the arcane formulae and elaborate theories of wizardry. The Witch's Handbook, like other books in the Master Class series, presents a brand new core class and an array of associated prestige class. In addition to the new feats, spells, and magic items that you'd expect, The Witch's Handbook explores the deeper secrets of the The Craft. Learn of covens and their ritual magic, charms and their making, and herbs and their magical applications. Whether you're a player looking for a different kind of magic user or a GM looking to add something new to your campaign, The Witch's Handbook has everything you need to bring The Craft to your d20 game.
