The Trebors are in more danger than ever before. The tribe is divided, Mt. Bor spits fire as its caverns boil, and the Borian Sea holds a secret of its own. When the malpeds flew away with seeds from the great tree, scouts are sent to retrieve them, but the power of the seeds is so great they grow immediately into a field of fledgling trees. Within days, the tribe is divided between those seeking a new way of life in the field nestled at the foot of Mt. Bor, and those choosing to stay with the great tree. But this divide has grave consequences, and life in the shadow of Mt. Bor is not what it seems. Determined to bring the tribe back together and stop the forces that threaten the Trebors' peaceful way of life, Stella leads the Trebors into their fiercest battle yet. Can they bring everyone home to the great tree and stop the malpeds once and for all? Or is the tribe divided forever and the mysteries of Bori a force too great to ever be stopped?
