So I guess I want to talk about the way Scalzi went about showing the reader his premise, and how the different levels of meta-narrative become apparent as you go along.
It starts right in the prologue, of course, where we have a character in a stereotypical Star Trek away mission scenario, who appears to be acting in ways even he doesn't understand and receiving knowledge that he didn't have before. It starts to come across there that this scenario is in some way manufactured, that they're being forced to play this role. The cliched encounter is made much more interesting by being in the head of an
unwilling participant.
In the early chapters Scalzi continues to reinforce to the reader that what is happening is pretty much exactly the setup of a sci fi TV show: the commanding officers going on away missions and people always dying; the part with the impossible science and the Box, and particularly the way the result from the Box needs to be delivered with a problem for Q'eeng to solve.
The final piece that solidifies the idea in the reader's mind is when Jenkins appears and delivers his warning: "Avoid the narrative." This means nothing to Dahl and Finn, but it's a clear suggestion to the reader: They are literally part of a science fiction story.
The next level of meta becomes clearer in the away mission with the killer robots. Here is where Crewman McGregor makes the first mention of the Sacrifice Effect, and then promptly dies. This clues the reader in to the fact that the crew have worked out the rules - but it also does something else. It was a moment of
fridge brilliance for me: I realised the next day that the Sacrifice Effect
was working for Andrew Dahl. McGregor dies from Dahl's party, and everyone else is safe - he was the sacrifice for Dahl.
That's the point where the reader gets a clue that this story isn't just lampshading and parodying these tropes, but is making active use of them for its own main characters. That's when I knew one of the five main characters had to die before the end. That's why, when they go back in time, they have a 6 day time limit - and why the people there buy into their story so quickly. It's why the solution to saving Matthew is nonsense science that uses the magic Box.
It's an interesting move, as it's an author deliberately making the reader aware of his hand behind events, that this narrative is something he controls - and deliberately making the reader aware of the author's hand takes a fair bit of confidence in your storytelling capabilities.
The book rewards the reader for paying attention to details and patterns. I first noticed that Hester didn't have a first name during the scenes of planning their mission with Jenkins: the characters kept calling each other by first name in their conversations, except for Hester.
Scalzi puts up a chekhov's gun in the form of Hanson's rich father and family connections, then leaves the attentive reader waiting for it to come into the plot, only for it not to happen - a deliberate subversion.
And then both of these things - Hester's name, Hanson's backstory's irrelevance -
become plot points in the story. It's brilliant, it's Scalzi saying direct to the reader
I know exactly what I'm doing. The little things that stick out as being odd, or cliched, or predictable, turn out to be there so that Scalzi can turn out yet another layer of meta-narrative on top.
It's hard to find fault in a book where you suspect the faults all happened knowingly.
