The six books of Anne McCaffrey and Elizabeth Ann Scarborough's Petaybee series are divided into two trilogies: Petaybee and The Twins of Petaybee. The protagonist of the first is Yanaba "Yana" Maddock, a soldier sent to the planet of Petaybee when injuries from a terrorist attack make it impossible for her to continue in the army. In the second trilogy, the central characters are Yana's children, Ronan Born for Water and Murel Monster Slayer Maddock-Shongili.
In all six books, the plot is basically the same: the planet must be protected from Intergal, an interplanetary company that wishes to relocate the inhabitants so it can mine for valuable minerals.
The series is not nearly as well known as the McCaffrey Dragonriders of Pern books, but is often considered to be of greater quality, as a whole.
Books in this series:
- Powers That Be (1993)
- Power Lines (1994)
- Power Play (1995)
- Changelings (2005)
- Maelstrom (2006)
- Deluge (2008)
This series contains examples of:
- Departure Means Death: Any native of Petaybee over a certain age cannot leave the planet's surface (due to adaptations that allow them to live comfortably in the planet's sub-arctic climate). Organ shutdown and death will occur within a matter of days.
- Genius Loci: The planet Petaybee was 'awakened' through the terraforming methods used to make the planet habitable by humans and communicates with its inhabitants through hallucinations that are given through a network of special caves. It's also capable of changing the climate/topography of the land when it's so inclined to benefit its inhabitants or drive off bad guys. The first several books hinge around the Company who terraformed the planet trying to recoup its investment and the inhabitants' efforts to convince them of the planet's sentience.
- Lighter and Fluffier: The Twins of Petaybee trilogy is not as dark and serious as the first three books.
- The Lost Lenore: In Powers That Be, the death of Yana's first husband is suggested to be the reason she joined the InterGal's military in the first place (which led to the injuries that led her to be shipped to Petaybee, the company's version of a desk job in a podunk town). Her growing feelings for Sean Shongili bring back memories of Husband #1.
- Mama Bear: Yana becomes a fierce protector of her children.
- Mega-Corp: Intergal. The central conflict of the first book is its claim of ownership over Petaybee vs. the heroes' arguments that Petaybee is a living being and cannot be owned.
- Menace Decay: Dr. Luzon and Intergal are formidable foes early but lose their teeth in later books.
- Powers That Be: Intergal again. Also the living planet itself ('Petaybee' is evidently derived from the initials PTB).
- Raised by Wolves: 'Cita grew up among insular religious fanatics.
- Reality Ensues: Once word of Petaybee's special status gets out, the planet is swarmed with new visitors (a rush covertly encouraged by InterGal): some lured to Petaybee by it's novelty (and completely unprepared for actual life on the planet), some looking to this new type of life as some sort of new holy figure, others still seeing new types of flora and fauna to collect (or in the case of the latter, just hunt). The locals are overwhelmed trying to protect the native life from the interlopers (and vice-versa).
- Second Love: Sean Shongili becomes Yana's second husband and their children are the protagonists of later books.
- Selkies and Wereseals: The series employs the selkie myth in a futuristic setting. The Shongili family uses genetic engineering to create a selkie (Sean). Sean's kids are natural-born selkies as well. There's a hint from Sean that his grandmother was a selkie. He says she "taught him how to swim", with a significant wink at Yana.
- Spin-Offspring: The second trilogy's protagonists, Murel and Ronan, are the offspring of the first trilogy's protagonist, Yana.
- Touched by Vorlons:
- Petaybee changes those who live on it to allow them to live comfortably in the planet's sub-arctic climate.
- Sean Shongili was further altered to be able to transform into a seal-like creature. (The reason why isn't really explored to any depth.)
- Unfortunate Names: The cult that raised 'Cita gave all of its girls humiliating names, until they "came of age" (read: became old enough to join the leader's harem). 'Cita's name was "Goat-Dung."
- Unto Us a Son and Daughter Are Born: Yana's twin children, Murel and Ronan
- Villain with Good Publicity: The Intergal corporation is predatory to say the least, but they have a reputation as a force of good.
- Wasteland Elder: Clodagh is the de facto leader of her village (main location of the first trilogy), possibly of all of Petaybee.
- Would Hurt a Child: 'Cita's cult forces all women of marriageable age to accept the 'honor' of being the leader's wife, with 'any time after puberty' apparently being old enough.
