The Skies of Pern strikes me as analogous to a flight of inexperienced dragonriders, each of whom independently tries to burn every bit of thread falling from the red star, resulting in a great deal of confusion and not exactly 100% success. It seems as though McCaffrey is struggling to come up with enough story lines to fill a novel and, while she does achieve that goal, she fails to integrate the various stories into a composite whole. Were this book a student essay, I would have to say that it lacks unity.
There are several potentially wonderful narrative themes in the book. We have the sabotage and vandalism wreaked by the Abominators, who are determined to stop and reverse the many technological innovations initiated by AIVAS, the artificial intelligence system brought by the original colonists and lately rediscovered. We have the huge tsunami generated by the impact of a comet fragment that plunges into Pern's sea and the heroic efforts of the dragons to rescue the land bound holders. We encounter the depredations of the giant felines on the Southern Continent. Running somewhat weakly through everything else is the angst of the dragonriders who fret about what they will do, now that threadfall is nearly at an end forever.
Except for the dragonriders' fretting, which grows quite tedious, any of the story lines could have been detailed and developed into a wonderful novel-length work, but none is pursued to any great depth. Instead, they are strung together like a weakly constructed anthology of unrelated events. This is not to say that the book does not have some delightful high points, both dramatic and humorous. The result of Golanth's first "heavy-handed" attempts to practice the dragons' newly recognized skill of telekinesis by moving trundlebugs is hilarious. The dialog (dragonlog?) between Golanth and Zaranth is frequently amusing and often touching. The terror and drama of the felines' attack on Golanth, his rider F'lessan, Zaranth, and her rider Tai are well delivered, and the novel becomes a veritable page-turner at that point. Unfortunately, we are then nearing the end of the book and are disappointed that the increased tempo is over so soon.
I have enjoyed reading almost all of McCaffrey's books, and I would not have wanted to miss The Skies of Pern. Still, I wish that it had become three different novels, each one dealing with one of great story lines in depth. The fourth line, that of the dragonriders' search for a meaningful existence in the post-thread era, would be better forgotten entirely. Turning them all into astronomers is not precisely a convincing solution to their pending unemployment problem. Still, for its faults and weaknesses, The Skies of Pern deserves to be read by those who have come to know the dragons of Pern. Newcomers to the series, however, will be more pleased to seek out McCaffrey`s earlier works on this fascinating planet.
