Maelstrom (2006) is the second SF novel in the Twins of Petaybee series, following Changelings. In the previous volume, Murel and Ronan barely saved the sacred Honu from Dr. Mabo and then immediately returned to Petaybee. Their father had gone missing and Madame Algemeine shipped a load of helicopters, small submarines and other rescue equipment to search their planet. Ke-ola and the Honu were also coming with them.
Back on Petaybee, the twins soon recovered their father, alive and well, but without any memory of his ordeal. Later, the Petaybeans took Ke-ola and the Honu into the communion cave and there they received a message from the planet. Petaybee wanted to invite Ke-ola, the Honu and their people to come live on the new landmass and the twins have been selected as planetary emissaries.
In this novel, the selkie twins and Sky Otter leave their homeworld to deliver the invitation. On the outward journey, the captain of the Piaf, Johnny Green, arranges for them to learn various ship functions. They never really have time to get bored.
After reaching the Halau system, the Piaf encounters the Intergalactic Enterprises Company Corps carrier George Armstrong Custer, Colonel Zachariah Cally commanding. The Intergal crew orders them to leave, but Marmion uses her rank and reputation -- and an outright lie -- to overrule the order and land on the planet. There they find Ke-ola's hometown deserted and full of craters from meteorites.
Although the situation looks hopeless, the Honu informs them that there are survivors underground. After the surviving villagers and Honus are found, Colonel Cally asserts that there are no more survivors. Yet the Honus guide them to another nearby village where other survivors of the bombardment have also gone underground. But the twins soon discover that this village has Manos -- sharks -- as their aumakuas instead of sea-turtles.
After considerable argument and with some rationing, the Piaf returns with these survivors to Petaybee. Since the spaceport is far from the sea, the Petaybeans make arrangements to transport the Manos -- with their able-bodied people -- to the ocean. Meanwhile, the young and elderly remain aboard the Piaf, but with better meals and other supplies.
In this story, the twins and Sky have another encounter with the sea otters. Then Sky casually mentions that the sea otters have told him that the deep sea otters are still alive, despite indications that a volcano had destroyed their city. Since nobody else knows that these otters exist, the twins decide to warn them about the sharks. Murel and Ronan head out to the new island forming in the sea where the deep sea otter city had been located.
The twins also encounter a number of other creatures in the sea, including a pod of Orcas, some sea seals, and the newly arrived Manos. Murel and the Orcas have a confrontation that isn't entirely one-sided. The sea seals are helpful, but a little domineering until they meet Sean and the Orcas. The Manos are bloodthirsty, but the patriarch is rather afraid of Murel.
This story is the middle book in a trilogy, so the ending leaves the situation hanging. The sentient planet Petaybee displays some of its powers, mostly at the end of the volume. However, one wonders whether the adult Petaybeans are ever going to be able to leave the planet without dying from their planetary induced changes.
Highly recommended for McCaffrey & Scarborough fans and anyone else who enjoys tales of sentient planets, telepathic animals and precocious selkie children.
