Changelings (2005) is the first SF novel in The Twins of Petaybee series. The planet Petaybee is eagerly changing the landscape. Recently it has been pushing up lava into islands. Eventually it will produce a continent in the tropics. A sentient planet is exciting to live on, particularly if it likes humans.
In this novel, Yanaba Maddock-Shongili has twins and the whole village of Kilcoole is eagerly preparing for the naming latchkay. Their father Sean leaves the babies with their guardians -- Nanook the track cat and Coaxtl the snow leopard -- and takes Yana into the kitchen to ease her hunger, then he sends her back to bed. After she has had enough sleep, Sean and Yana change the twins, wrap them up in furs and take them out to the latchkay.
The whole village meets to sing, dance and give gifts to the twins. After the giving of the gifts, the villagers traipse off to the communion place, where the twins are named and introduced to Petaybee. The twins terminate the ceremony by changing to baby seals and diving down the falls at the cave entrance, with their concerned father in hot pursuit in his seal form.
Although not readily apparent, the twins are telepathic with each other. Also, they can communicate with the animals around them. Maybe this ability has something to do with their faithful guardians. Nonetheless, Nanook and Coaxtl cannot swim as well as the kids and Sean is too busy governing the people on the Petaybee to have the time to swim with them.
Ronan is also having trouble remembering to hide his clothes before he changes into a seal. Murel doesn't have this problem, but both could use some waterproof clothing to take with them on long swims. When they bring up the problem with their (adopted) Aunt Marnie, she finds some suitable apparel being produced by one of her plants and sends some to the twins.
Now that the clothing issue is solved, Ronan and Murel still need a swimming companion to accompany them on long trips. They meet the perfect candidate one day as they are exploring the river. The otter is somewhat anxious when they share their dual nature with him, but soon Otter becomes a good friend and introduces them to his family.
On another swim down the river, the twins discover that their otter friends are gone. Otter himself finds them later and tells of the scent messages left behind by his family. Some humans have captured the family and removed them from their caves. Ronan and Murel hurry back to their father and report the problem. He gathers a posse and the colonists free the captured otters and hustle the poaching scientific team off the planet.
Yana and Sean realize the danger to their offspring from these criminal scientists and sends off the twins to Aunt Marnie's headquarters in an artificial satellite. The twins enjoy the people and activities in the headquarters, but they are not safe even there. Soon another attempt is made to capture the twins. Fortunately, the kidnappers are not aware of the twins's telepathic abilities.
This story is a continuation of the Petaybee trilogy, featuring the next generation of Shongili selkies. Ronan and Murel have all the talents of their parents, but none of their experience. But Sean and Yana try to teach them as much as possible about sneaky, conniving humans and the twins are quick studies.
The planet is not supposed to have been inhabited, but Sean accidentally discovers a group of sentient deep sea otters living on the slopes of an erupting volcano. He doesn't remember the incident, but the twins do. Nonetheless, the twins are convinced that this group has perished in the eruption, but is this so?
In this story, the scientists trying to investigate Murel and Ronan are very much stereotypical hard-hearted individuals, putting their scientific studies above any considerations of compassion or fairness. Maybe this group is inconsiderate of animal fears and pains, but not all scientists are this ruthless. Other authors are themselves biologists, but portray their characters as diverse individuals with varying degrees of concern for animal emotions. A few counterexamples to these stereotypes would be appreciated.
Highly recommended for McCaffrey & Scarborough fans and for anyone else who enjoys tales of exotic societies, telepathic abilities and unusual creatures.
