When McCaffreys beloved dragons roar and their riders soar on the beasts mighty backs .

fans of Pern will likely be enthralled.

-- Publishers Weekly For generations, the dragonriders had dedicated their lives to fighting Thread, the dreaded spores that periodically rained from the sky to ravage the land.

On the backs of their magnificent telepathic dragons they flew to flame the deadly stuff out of the air before it could reach the planets surface.

But the greatest dream of the dragonriders was to find a way to eradicate Thread completely, so that never again would their beloved Pern be threatened with destruction.

Now, for the first time, it looks as if that dream can come true.

For when the people of Pern, led by Masterharper Robinton and Flar and Lessa, Weyrleader and Weyrwoman of Bendon Weyr, excavate the ancient remains of the planets original settlement, they uncover the colonists voice-activated artificial intelligence system--which still functions.

And the computer has incredible news for them: There is a chance--a good chance--that they can, at long last, annihilate Thread once and for all.
