Also published as "Dragonseye". For two hundred years there had been peace on Pern, but now the signs were ominous. Violent winter storms and erupting volcanoes heralded the coming of the second Pass of Thread. 1997.

Xhinna, the first female Weyrleader, and her group of young dragonriders struggle to rebuild the decimated dragon population and protect the world from a deadly alien spore by collecting dragon eggs and protecting baby dragons from predators and saboteurs

Scores of dragons are dead after plague swept across the world of Pern, and now the Weyrs are struggling to rebuild before Threadfall destroys everything--and everyone--left alive. Their best hope lies with a group of new dragonriders who have volunteered to brave the dangers of an unexplored island populated by vicious wild felines and voracious tunnel-snakes to create a safe home for their young dragons, whose offspring will hopefully replenish Pern's decimated population. But their leader, Xhinna, the first female rider of a blue dragon, faces an uphill battle to win the respect of her peers, especially after tragedy leaves the new colony reeling. The way forward seems to lie with the awesome ability of the dragons to travel through time. But that power comes with risks: By venturing into the past, Xhinna may jeopardize the very future she has sworn to save.

Even though Lorana cured the plague that was killing the dragons of Pern, sacrificing her queen dragon in the process, the devastating disease has left too few dragons alive to fight the fall of deadly Thread. As morale at Telgar Weyr plunges in the wake of the widespread loss, and Weyrwoman Fiona and the harper Kindan struggle to keep hope from vanishing, a pregnant Lorana decides she must take drastic steps. Nothing short of manipulating time itself will undo the damage done by the plague. But attempting time travel could have devastating consequences--altering history, and destiny, forever. Now, somehow, Lorana must find a way to accomplish what seems impossible: bending the natural laws of the universe without wreaking havoc on existence itself. To ensure the future of Pern, she's willing to take the fateful chance--even if it demands yet another, far greater, sacrifice.
