Dragonsdawn

Dragonsdawn is a science fiction novel in the Dragonriders of Pern series by Anne McCaffrey. It was first published in 1989. While the Dragonriders of Pern series is recognized as science fiction (due to its origin discussing the nature of the star Rukbat and its planetary system), many of its elements in the earlier books were primarily fantasy in origin. Dragonsdawn clearly establishes the science fiction nature of the series by defining the science behind Anne McCaffrey's dragons.
