This is the first novel in a classic series, and various books in the series have own a bucketful of awards. This novel reads like a fantasy, and you think that is what it all is about until later in the series when it becomes a science fiction theme. Dragons in this case are winged beasts who can breathe fire and burn the "thread", a deadly enemy that periodically falls from the sky. Lessa, a young lady, has certain mental powers that she puts to work getting revenge on the people who invaded her family's domain, and tries to use those powers on the Dragonriders when they come around. This brings her to their attention, and she become a Dragonrider herself. While I like it a lot (and so do many others when you look at the awards McCaffrey earned), I would not recommend it to someone who does not enjoy fantasy. The science fiction aspects do not come out until later in the series.

I have this as part of the three-volume set The Dragonriders of Pern which includes the first three novels in the series.
