This is a very accessible and entertaining Heinlein read. 
It is set in what was then a couple of decades into the future: 1970. The protagonist ends up travelling 30 years into his future by means of a cryogenic sleep to wake up in the year 2000. Reading this book in the year 2015 gives one quite a different perspective than one would have had reading it when it first came out. One can look back and judge how the authors vision of those years diverged from reality.

The first time I read this book was years ago at the suggestion of a boyfriend and I don't know if that colored my opinion of the book or what, but I thought it was merely okay/didn't really like it. But in rereading, I find I have a much better opinion of the book and I'm not sure if it's just that I understand it better, having had that first experience, or if my tastes have changed since then (in boyfriends as well as books ;).

I haven't previously managed to get through any of Heinlein's work, but I am nothing if not determined, so I finally picked this up and decided to have a jolly good go. And it was okay. The style is easy to read, conversational; matter of fact, even. It's almost not like reading a story, except of course you know that few of Heinlein's predictions work out (though he did predict the Roomba).
It's an interesting take on cold sleep/time travel, and a personal one. Dan isn't saving the world, he's j ...more

ah, Heinlein: when he's not completely off the fucking deep end into icky-sex territory(1), he's such a fun writer. I think a lot of times, the kookoo stuff in his later works overshadows his body of work as a whole, so it's nice to come back to one that's fairly free of insanity(2).
in classic Heinlein fashion(3), our protagonist is a salty, quick-witted, ex-military man, equally keen on being his own boss as he is on the aerodynamics of a woman's brassiere. he's an engineer working on household ...more

A sports car on a twisty road of a time travel story, breezy and fun. I love reading (and rereading) the near-future SF classics to see which predictions have come to pass, and which have not. This one was written in the 1950s and set in 1970 and 2000, which gives both futures a House of Tomorrow hue, complete with house robot. Heinlein also predicted bellbottoms coming into fashion, though in the wrong future. The plotting is tight and clever, and the main character and his cat are worth rootin

Heinlein at his good-story-ruined-by-misogynist, dirty-old-man, creepyness. The usual in other words.
