Shortly after Fiona's return to Fort Weyr, three Turns older and wiser, her queen, Talenth, is infected with the dreaded sickness that has consumed so many of Pern's precious fire-breathing dragons. Talenth's recovery and the recovery of all the other dragons of Pern is delivered by the unflagging efforts of Lorana and Kindan at Benden Weyr - but their one vital clue is only bought with the loss of all the dragons of Telgar Weyr.
Fiona is sent to relieve the distressed weyrfolk of the now-dragonless Weyr. When her queen, Talenth, rises to mate, Fiona finds herself not only Telgar's senior Weyrwoman but in the center of the dilemma that confronts all Pern - how can the one thousand fighting dragons do the job of three thousand? And, if they can't, how long will it be before all of Pern is consumed by Thread?
Older and wiser after three turns in the past, young Weyrwoman Fiona and Talenth, her golden queen dragon, return to continue the fight against the deadly Threadfall in McCaffrey's romantic, highflying sequel to Dragonheart. This time out the battle is made more difficult by a horrifying disease that is steadily killing off the dragons. Despite finding a cure, the fear persists that there won't be enough dragons to battle the next Threadfall. In the meantime, a kinky love quartette between Fiona, dragonrider T'Mar, Weyrwoman and ex-queenrider Lorana, and Harper/Weyrlingmaster Kindan creates friction, especially when both Lorana and Fiona become pregnant as threats to Pern increase. McCaffrey's assured characterizations and ease with referencing Pern's elaborate history make this a hardy fantasy that faithfully echoes and builds upon his mother's original vision.
Not as good as Anne's books on Pern. I keep going back trying to find the ties to that time as this helps develope the weyres and the attitudes to them for Lessa's time.
