The Talismans of Shannara (The Heritage of Shannara, Book 4)

The Shadowen still swarm over the Four Lands, poisoning everything with their dark magic. And their leader is determined to destroy all the Scions of Shannara. For Walker Boh, he dispatches the Four Horsemen. For Wren, he sends an untrue friend. And for Par, he devises the most terrible fate of all. With these traps cleverly laid, the charges given by the shade of the Druid Allanon are doomed to failure--unless Par can discover a way to harness the power of the Sword of Shannara.

Thus continues the enthralling Shannara epic, a spellbinding tale of adventure, magic, and myth...
