''The Tau Ceti Agenda Series'' is relatively hard military science fiction by author Creator/TravisSTaylor. In a somewhat dystopian future, politically the United States has changed a lot. Changes include no electoral college and no term-limited presidents. Has been described as "a sci-fi [[TwentyFour 24]]".
Each of the books contains the events of one very important day in the series timeline.
# ''One Day on Mars'' covers the 24 hours leading up to a key event on Mars and the events immediately afterward. A lot of people are caught up in the consequences
# ''The Tau Ceti Agenda'' covers an attempted assassination, a critical new technology used in combat, and and attempt to influence an election.
# ''One Good Soldier'' is much the same as the previous books, with critical events all happening in a single day.
This series provides examples of:
* ColonizedSolarSystem: Mars has been colonized long enough for people to have a particular phenotype (tall, pale, black-haired).
* TheConspiracy: What else can you call it when [[spoiler: Elle Ahmi]] is responsible for causing the entire military and political situation to further her agenda?
* DesignatedVictim: Poor Joe Buckley, the designated victim of choice among Baen authors ends up dead in a particularly nasty manner in the first book. In the following books, Joe Buckley Jr. comes pretty dang close to following in his father's footsteps a couple of times.
* TheEmpire: The United States, although technically a democracy, is now considered an empire. The various colonist groups, both within the solar system and outside it, find themselves almost without representation.
* EvilVersusEvil: You have TheEmpire US, who engages in the very practices that fomented the Revolutionary War, versus the Separatists, who massacre civilians by the boatload. Caught in the middle are decent people who are doing what they think is right.
* FantasticRacism: The Martian Separatists are derogatorily referred to as "Seppies", a term that the President during One Day on Mars refuses to allow his administration to use.
* OffscreenMomentOfAwesome: The series takes place over several years, but each book only covers 24 critically important hours. There are numerous references to battles that happen outside of the books.
