Volume II of The Dragonriders of Pern®, the legendary series by award-winning author Anne McCaffrey
Since Lessa and Ramoth, her golden queen dragon, traveled into the past to bring forward a small army of dragons and riders to save their world from deadly alien spores, fear and desperation have spread across the land. But while the dragonriders struggle with threats both otherworldly and human, a young rider named F’nor and his brown dragon, Canth, hatch a bold plan to destroy the alien scourge at its source—the baleful red star that fills the heavens and promises doom to all.
Good old friend
I read this book years ago as a teenager - rereading them again as a *gasp* middle-aged woman. I learned a lot about honor from these books and I value that!
