John Varley continues to channel Robert Heinlein, explore the implications of the "bubble" technology introduced in "Red Thunder," and follow the adventures of succeeding generations of the Garcia-Strickland clan.
Channel Heinlein: the heroine is named Podkayne, at one point she travels on the spaceship Rodger Young, and there's enough sex and nudity to kick this off any kids' reading list. Podkayne read "Podkayne," and vows not to read any more books by the author. Cute. Big government is diabolical. And the ending is another classic Heinlein event.
"Bubble" technology: there's a bit of revisionism about the device's invention and some suggestions that the technology is at least partly created by a mental effort. New uses and weaknesses are found.
And the third generation of the Garcia-Strickland family is in the thick of it all. Along with the Broussards. Especially Podkayne, who is a singer, a member of the Martian space navy's entertainment troupe. But on a trip to Europa, a Galilean moon of Jupiter, everything changes.
Alien life is a long-standing trope in science fiction. Will we recognize that lien life if we meet it? If that alien life lives in geologic time, and not human time, will we even be able to communicate? What will happen if we can't? There's a flavor, a hint, of Varley's Gaia Trilogy here.
Some of Varley's premises are a bit of a reach. And poor old planet earth, ravaged by the tsunami in "Red Lightning" and by global warming, gets whumped again. But it's a fun novel, if a bit slow in spots, and there is room for a couple more sequels, likely involving twin girls. I hope those hypothetical sequels can recapture the charm of the first book.
