===About the Book=== Anne McCaffrey's Pern is one of the most memorable worlds in science fiction and fantasy. Humans and their flying dragon companions live in fear of ''thread'', a caustic, deadly material that falls sporadically from space. But when the thread doesn't fall for a long time, people become complacent, forgetting that it is the brave dragonriders who can save them from the periodic threat. But when the thread falls, human and dragon heroes must fight the scourge. This edition encompasses the first three unforgettable novels of McCaffrey's epic series: ''Dragonflight'', ''Dragonquest'', and ''The White Dragon''.
