* AuthorsSavingThrow: In the afterward for ''Zoe's Tale'', Scalzi admits that a major motivation to telling a parallel story was to make Zoe returning with exactly what the Roanokers needed feel like less of a DeusExMachina. It also let him give some closure to the werewolves.
** ''Old Man's War'', as an homage to ''Literature/StarshipTroopers,'' was naturally committed to a CrapsackWorld view of the universe in which humanity's only options were extinction or perpetual warfare against any race capable of occupying Earth-like worlds. (Though even in that book, the StrawLiberal [[JerkassHasAPoint 'has a point']] and the Consu clearly aren't following the CDF's script.) ''The Last Colony'' inverts this bleak worldview entirely, suggesting that many alien races ''can'' come to long-term peaceable agreements about territory - which leaves the CDF an example of HumansAreTheRealMonsters.
