Craig Alanson's Expeditionary Force series opens with a premise that sounds straightforward — Earth gets invaded, Earth survives — and then immediately pulls the rug. The liberation was not what it appeared to be. Humanity is still a pawn in a conflict it does not understand. And the most significant development is not the alien contact or the military hardware: it is the discovery of Skippy the Magnificent, an ancient and incomprehensibly powerful AI who is also, somehow, insufferably petty and prone to long digressions about the cognitive limitations of humans.
The series works because Alanson plays the comedy and the military tension in the same register without undermining either. Joe Bishop — an Army sergeant thrust into command responsibility he was never meant to have — is a genuine everyman hero who earns every step of his authority through operational ingenuity rather than movie-protagonist luck. The tactical problem-solving is legitimate. The command dynamics are legitimate. The relationship between Bishop and Skippy is one of the best running dynamics in military sci-fi.
At 19 volumes and still ongoing, ExForce is a serious commitment. It earns it.
Start with Book 1 (Columbus Day) and read in order. This is a long-running series (20+ books) with a continuous storyline — you cannot dip in mid-stream. The audiobooks narrated by R.C. Bray are the recommended format for most readers.
