Dragons of Autumn Twilight (Dragonlance: Chronicles #1) by Margaret Weis, Tracy Hickman

Once merely creatures of legend, the dragons have returned to Krynn. But with their arrival comes the departure of the old gods—and all healing magic. As war threatens to engulf the land, lifelong friends reunite for an adventure that will change their lives and shape their world forever . . .

When Tanis, Sturm, Caramon, Raistlin, Flint, and Tasslehoff see a woman use a blue crystal staff to heal a villager, they wonder if it's a sign the gods have not abandoned them after all. Fueled by this glimmer of hope, the Companions band together to uncover the truth behind the gods' absence—though they aren't the only ones with an interest in the staff. The Seekers, a new religious order, wants the artifact for their own ends, believing it will help them replace the gods and overtake the continent of Ansalon. Now, the Companions must assume the unlikely roles of heroes if they hope to prevent the staff from falling into the hands of darkness.

Lifelong friends, they went their separate ways. Now they are together again, though each holds secrets from the others in his heart. They speak of a world shadowed with rumors of war. They speak of tales of strange monsters, creatures of myth, creatures of legend. They do not speak of their secrets. Not then. Not until a chance encounter with a beautiful, sorrowful woman, who bears a magical crystal staff, draws the companions deeper into the shadows, forever changing their lives and shaping the fate of the world.

No one expected them to be heroes.

Least of all, them.
