"Rolling Thunder (A Thunder and Lightning Novel)" by John Varley
https://www.amazon.com/Rolling-Thunder-Lightning-Novel/dp/044101772X/

Book number three of a four book young adult space opera series. I read
the well printed and well bound MMPB published by Ace in 2009 that I
bought used on Amazon since my books are packed in the garage and the
book is out of print. This is my third or fourth reread of this book.
I have a new copy of the fourth book in the series that I am reading now.

Each one of the Thunder and Lighting books highlights a new generation
in the connected families since the first generation of the connected
families in the first book. This book specifically covers Patricia
Kelly Elizabeth Podkayne Strickland-Gracia-Redmond, the first member of
the third generation who goes by Podkayne. BTW, Podkayne reads
Heinlein's "Podkayne of Mars" book and calls Heinlein a crazy old man.
And yes, there are serious Heinlein fanboy comments all throughout the
series as Varley is very heavily influenced by Robert Heinlein.

Podkayne is born and raised on Mars, a Martian. After all, two of her
grandparents were part of the first five people to step foot on Mars on
the first bubble drive spaceship. By the time she is an adult, there
are over million people living on Mars. At the beginning of the book,
Podkayne is a lieutenant JG, serving her mandatory two years in the
Martian Navy. She is currently serving that duty in California on Earth
as a local embassy officer. And then she recalled to Mars since her
great-grandmother has an untreatable medical condition and is going into
a stasis bubble until such time that a treatment is available.

My previous review of this book: "Book number three of a four book space
opera series. This is my second or third reread of this book, the
sequel to the sequel of one of my top ten all time favorite books. BTW,
I would characterize this book as young adult SF but not juvenile SF. I
get the feeling that there will not be a fifth book in the series as
Varley seems to be a movie reviewer nowadays.
Varley reduces the Earth population from billions to millions in this
book. I wonder where they all went ? (sarcasm)
I need a squeezer generator !"
