The Dolphins of Pern

Centuries ago, the first colonists of Pern dreamed of a new life, but a deadly threat called Thread forced them into a desperate struggle for survival, and their intelligent dolphin partners were forgotten. Now, as the dragonriders prepare to end the Thread threat forever, a young rider named T'lion and his friend Readis reconnect with the legendary dolphins. Together, they must revive the bond between land and sea dwellers and resurrect the original colonists' dream.
