My first SF book was Anne's "Nimisha's Ship" actually

It got me hooked to SFF. The Pern books followed, I think it was the Moreta one first.
I agree with manephelien. I think it was better without the tech they discovered. It just seems wrong to have computers on Pern >.<
I loved All the Weyrs of Pern because it was a good story but hated the consequences.
