What it's about
On his 75th birthday, John Perry visits his wife's grave and joins the army. The Colonial Defense Forces recruit only senior citizens, who sign up hoping they'll be made young again to fight humanity's wars among the stars. They are, in a way Perry never imagined, and then they're sent into a galaxy full of aliens who want the same planets we do.
Why it's worth reading
It was Scalzi's first novel, a Hugo finalist and a modern classic of military science fiction. It's fast and funny, with real emotion underneath.
