NATIONAL BESTSELLER • “Captivating . . . The McCaffreys are well known for their brilliant characterizations, and they do not disappoint here.”—Booklist In Fort Hold, a clutch of fire-lizard eggs is about to hatch, and Lord Bemin’s beautiful young daughter, Koriana, is determined to Impress one of the delightful creatures. At the hatching, apprentice harper Kindan Impresses a fire-lizard of his own . . . and wins the heart of Koriana. But Lord Bemin mistrusts harpers and will not hear of a match between his daughter and the low-born Kindan. Then fate intervenes in the form of a virulent plague as fast-spreading as it is deadly. Arising suddenly, as if out of nowhere, the contagion decimates hold after hold, paying no heed to distinctions of birth. In this feverish crucible, friendship and love will be tested to the breaking point and beyond. For with Threadfall scant years away, the Dragonriders dare not expose themselves to infection, and it will fall to Kindan and his fellow apprentices to bravely search for a cure and save humanity.  “Strong storytelling and compelling drama, along with memorable characters.”—Library Journal
