Old Man’s War by John Scalzi.
I’ve been reading the Hugo nominees for best novel, and this was the last one. The blurb states “
Though a lot of SF writers are more or less efficiently continuing the tradition of Robert A. Heinlein, Scalzi’s astonishingly proficient first novel reads like an original work by the late grand master
Since my taste runs more to Bill, the Galactic Hero, I’m not exactly the target market. On the other hand, having read Starman Jones to the point where I could recite the text when I was 14, I’m not totally ignorant of Heinlein either.
In terms of the standard features, Scalzi doesn’t do a bad job. We get the recruiting office, a pretty good drill sergeant from Hell, the usual battle scenes and the inculcation of a military ethos, along with a recognition that “War is Hell”. Heinlein fans will love all this. And there’s the twist in the title. The colonial defence forces only recruit 75-year olds, for reasons that are explained a few chapters into the book. {The later appearance of the Ghost Brigades (I’ll avoid a spoiler on this), seems to me to undermine the rationale, but maybe this will be explained in the subsequent eponymous book.}
Where the book fails, in my view, is as hard science fiction. As you’d expect from the genre the underlying view is what might be called interstellar realism; the galaxy is a tough place and there are a lot of species out there eager to seize our planets and eat us. But Scalzi gives no answer to the Fermi problem: how come the neighbours haven’t already dropped in for dinner, instead of waiting for us to go out to meet them. And even when the book is set, Earth is mysteriously immune from external attack, despite the absence of any of the defence forces that are needed everywhere else.
Then there’s Earth itself. The book is set at least a couple of hundred years after Earth has developed an interstellar space drive, but apart from that it could be set in 1990 (in fact, apart from a passing reference to an office computer, it could be set in the 1950s). The hero is a retired advertising agent, and his companions have similarly 20th century jobs. He produces a driving license as ID, signs up in a strip mall and takes a plane to the spaceport.
I know you’re supposed to suspend disbelief, but all this goes beyond my capacity, I’m afraid.
