A decent, antimilitaristic space opera romp with shades of everything from "Starship Troopers" to "Gulliver's Travels." Jim di Griz is a wisecracking, planet-hopping young buck with a taste for adventure and a knack for getting into trouble. Through convoluted circumstances, he gets involved in an intergalactic conflict that involves a libertarian-inclined civilization invaded by a nation of interstellar Spartans whose martial obsessions with killing and conquest turns young di Griz's stomach.
Harry Harrison, the book's author, is a military vet and it shows in his distaste for the kinds of careerists and sadists who populate the higher echelons. Vets will recognize the architypes, and if they're unlucky enough, maybe even themselves. I certainly don't miss those days.
The humor works sometimes, and at other times falls flat. Ditto for the satire and social commentary, which can be trenchant but is more often belabored. "Stainless Steel Rat gets drafted" is the second in a series, but can be read as a standalone, since every character has a past and therefore every tale is told in media res.
My copy includes an excerpt from Harrison's "Return to Eden," a sort of "Lost World" riff that tries to imagine what might have happened if the extinction event hadn't snuffed the dinosaurs, and the saurian survivors somehow grew sentient enough to go to war with Homo Sap. A promising premise, maybe, but I'm not rushing to my used bookstore to scour the shelves after "Stainless Steel." To each their own, however.
