Young Fiona, rider of the gold queen Talenth, has returned with the dragons and riders who fled into the past to heal their battle wounds and prepare to fight anew the menace of Thread. Now more than three years older, Fiona is no longer a child but a woman—thrust into authority by a shocking tragedy. But leading weyrfolk who are distrustful of a young outsider will be only one of her challenges. Despite gaining reinforcements from the past, too few dragons have survived the recent plague to stem the tide of the intensifying Threadfall. As a senior Weyrwoman, Fiona must take decisive action. With the aid of Lorana, the rider who sacrificed her dragon for others, and Fiona’s true love, the harper Kindan, she proposes a daring, nearly impossible plan. But if it succeeds, it just might save them all.
