Maelstrom — Anne McCaffrey; Elizabeth Ann Scarborough

The sentient planet of Petabyee has agreed to harbor a group of new refugees, workers indentured to the powerful InterGal Corporation: But the mission to collect the immigrants becomes a rescue operation when it is revealed that InterGal is doing nothing to help these survivors of a world devastated by a meteor shower. The telepathic, shapeshifting twins Murel and Ronan set out to persuade the frightened refugees to come out of hiding, leave their world, and bring along their sacred totem animals. But the twins have taken on more than they expected: The sacred animals include Manos, intelligent sharks who have lost none of their predatory habits.

When the Manos are released into Petaybee's waters, a tragic misunderstanding threatens to ruin the entire resettlement operation. Now Murel and Ronan must smooth the waters before a maelstrom of revenge destroys Petaybee's harmonious way of life.
