Why it endured
75-year-olds are recruited into an interstellar military and given new young bodies. Scalzi's debut is a loving homage to Heinlein — funny, fast, and surprisingly thoughtful.

“This is a humorous medium-ambitious space opera sci-fi. As far as ideas and world building go, I enjoyed some of the concepts (e.g. "smart blood"), but found others highly naive / dubious (silly biological aliens, etc). The story is enjoyable, but doesn't try too hard to wow. Overall, a satisfying bite of a story-driven sci-fi if you can forgive the unrealistic universe. 3/5”
