The Counterfeit Heinlein was the third Gerald Knave novel that Janifer had published, and it came out twenty-some years after Ace published the first two in the late 1970s. It seems to me to lack continuity with the prior books; Knave is just a futuristic private eye on an alien planet and the whole "survivor" concept is lost. The mystery itself is satisfactory, entertaining but not surprising. Recursive science fiction is easy to write, as (I think was Mike Resnick) has pointed out, but very difficult to write well. Janifer's foray into sf fandom satire verges on fanfic, as perhaps it should, but the idea that fannish activities will remain unchanged after an apocalyptic event ravishes Earth, three hundred years in the future after interstellar colonization... well, the only thing that seems less likely is that niche pop-culture icons from the mid-twentieth century will still be familiar to the inhabitants of that future. Perhaps I'm disappointed because I wanted to like the book a lot more than I actually could. I'll say two-and-a-half stars and round it up for the effort.
