From publisher blurb:

A Spell Is Better than a Thousand Words

Every mystic library reserves a place for this single potent volume of arcane lore. It's packed with ways to customize sorcerer and wizard characters, including:

• New feats, spells, and magic items.
• New prestige classes, including the dragon disciple, fatespinner, and pale apprentice.
• Information about special organizatinos such as the Broken Wands and the Arcane Order.
• Maps of a mages'guildhall and a home that a sorcerer and a wizard share.

Tome and Blood is indispensable to players and Dungeon Masters who want to add a new dimension to sorcerers and wizards.
