3.5 StarsThis is my first Robert Heinlein book. Though I intended to start with [b:Stranger in a Strange Land|350|Stranger in a Strange Land|Robert A. Heinlein|http://d.gr-assets.com/books/1156897088s/350.jpg|908211] or [b:The Moon is a Harsh Mistress|16690|The Moon is a Harsh Mistress|Robert A. Heinlein|http://d.gr-assets.com/books/1348768309s/16690.jpg|1048525], I saw this little paperback in my local library, and picked it up on a whim.Most of the retro science fiction that I've read thus far has been limited to women: [a:James Tiptree Jr.|1065820|James Tiptree Jr.|http://d.gr-assets.com/authors/1212550269p2/1065820.jpg], early [a:Nancy Kress|21158|Nancy Kress|http://d.gr-assets.com/authors/1232323985p2/21158.jpg] and [a:Octavia E. Butler|29535|Octavia E. Butler|http://d.gr-assets.com/authors/1242244143p2/29535.jpg]. So a Heinlein's viewpoint was refreshing (in a sometimes condescending 50's man kind of way).This book, written in the mid 1950's, is set at first in 1970, and later in 2000. It has love, betrayal, cryogenic sleep, revenge, time-travel and plenty of gadgets. i.e. something for everyone.
