Review:I first read this book when I was a young teen. After many years, I pulled the book off the shelf and read it again. It is an entertaining and fun read. The twins, Castor and Pollux, their Father Roger, and Grandmother Hazel are well written, interesting characters. Meade, the sister, and Edith,their Mother, are poorly written side characters. Edith is a dedicated and hard-working doctor, but her character doesn't have much personality.

While the book stirs the imagination and is humorous... Read more

Review:Classic Heinlein Juvenile. Read it when I was a bit younger then I am now and every now and then I read it again. Gives an interesting insight into the rivalry between twins with a side story of traveling to the stars. Read more

Review:Robert Heinlein's vision of life on Mars in this book is, from a scientific standpoint, way off, but the story he tells of two young men fighting to keep that life safe for their family and friends (with help from some of the native Martians along the way) is an interesting, funny, exciting, and wholly enjoyable one. There's even a bit of a mystery along with all the atmosphere and adventure. This is the sort of Heinlein book that one can't help smiling at the thought of.

Heinlein just ha... Read more

Review:First, the best. Heinlein writes more vividly and with better style here than he did in any novel before or after. Only some of his crackerjack short stories and novelettes compare to the pacing and clever plotting found here. Like other sf writers in the 60s, he started responding to the more "respectable" literature outside the field, and unless I miss my mark was influenced by the bastardized Russian of Burgess's A Clockwork Orange (1962). Indisputably the best character in this novel (as... Read more

Review:In the early 1940's, Robert A. Heinlein began writing a series of stories in a scenario called "The Future History" series.* He developed a historical timeline of this alternate history, along with description of future events, characters, historical trends, and stories yet to be published. By about 1950, Heinlein had pretty much completed the Future History project. But late in his career, Heinlein wrote a _coda_ of sorts to his Future History tales, _Time Enough for Love_ (1973). It featured h... Read more

Review:I feel like a grain of sand reviewing a Heinlein novel! I do like his " this is the way it is" tone, but find the plot lines jolting! The future of Methuselah's Children is technologically advanced, but this leads to overly explained space flight that is tedious. If you love the unexpected, however, get ready for the bumpy ride!

Review:This is my FAVORITE HEINLEIN book, 2nd Only to GLORY ROAD!! For those who condemn this work, perhaps they haven't grasped all the concepts behind it? Although it is true that Heinlein's early works are his best, this IS ONE OF HIS BEST BOOKS, BAR NONE! I first read this book over 20 years ago, not long after it was first published, and I am HAPPY to read it again today in July 2010! I have give COUNTLESS paperback copies of this book to friends throughout the years, as it is one story I most... Read more

Review:As a Heinlein fan and a lover of classic sci fi, I was happy to find this (especially after having seen all the good reviews). Then oh so disappointed. This is basically the diary of a young Martian lady, her younger brother occasionally adds comments. The story starts out inane and repetitive, then becomes dismally boring and finally just dismal. If anyone else had written it, I would not have bothered to finish. What a waste of time and money. Read more

Review:There are many aspects to this book that is not meant to be taken seriously. Except for one thing: Heinlein, I think, knew a lot about cats. I finally got my first cat six years ago and she is not quite like Petronius the Arbiter, Pete for short, in the book. Since I got her from a shelter, she had to be neutered, an absolute no-no for Pete (and, perhaps, Heinlein's own cats).

I enjoyed all the passages where Pete is present and active the most. OK, time travel back and forth twice (not e... Read more
