4. Columbus Day (The ExForce Series #1)

Craig Alanson - 2017 


Aliens attack on Columbus Day. The aliens are rearing for war and are technologically superior in every way. But quickly a new force shows up scaring the invaders away. But are these new allies truly allies? The irony of the timing is not lost on the characters. Foreigners with better technology invading another population only to have a third party enter the scene? Yeah, that fits the history books' version of 1492, too.

The story is told from the perspective of Joseph Bishop, the main character. Bishop is part of a UN Expeditionary Force tasked to face down the enemy. The action is written in a gripping style. The humor, though invited, often misses the mark.

Check it out here on Goodreads.


21. The Praxis (Dread Empire's Fall, #1)

Walter Jon Williams – 2002  


The universe is under the tyranny of the all powerful Shaa. But the cracks are starting to show. The downfall of the empire brings the hope of a new and fair order. But it also threats terrible, bloody chaos. Follow the travels of Lt. Gareth Martinez and Pilot Caroline Sula in their adventures.

The characters are realistic and believable. Many remind me of Tom Wolfe's A Man in Full by way of self-loathing in one moment only to self-aggrandize another. The scope of the series is quite vast as well and a wonderful read.

Check it out here on Goodreads.


22. Starship Troopers

Robert Heinlein - 1959


Robert Heinlein is a known name on the sci fi scene. In particular, his heralded (and despised depending who you ask) book Strangers in a Strangeland had heads turning. Shockingly, the Starship Troopers story was written in 2 weeks and was first published as 2 unique magazine articles. It is a decently fast read at just over 250 pages.

The book follows a character named Juan Rico, a recent high school graduate who joins the "Federal Services" (AKA the military) in light of an alien threat. While facing the Arachnid (the alien threat), Rico deals with difficult training, feelings of belonging, and challenging family dynamics. Readers beware: This isn't escapism. This isn't Star Wars. True to form, Heinlein's writing is a commentary on real-world themes like imperialism and societal destruction through moral decay.

23. Their Master's War

Mick Farren - 1987  


Primitive people are taken from earth to serve an alien race called Therem in their ongoing wars and battles. The captives decide to rebel against their masters and free themselves to go out on their own.

Farren spins a fast-paced storyline with captivating characters. The narrative explores the cynical attitude of soldiers fighting a pointless war. The twists and turns of the plot pay off well.

24. Unbreakable (Chronicles of Promise Paen #1)

W. C. Bauers - 2015  


Stuck between two fighting human empires, the colonists of Montana are shook when their world is the scene of an explosive event threatening to send the galaxy into war.

The invention of the jump drive has opened the whole universe to human exploration. But with the discoveries, law and order dictated by earth has ended. Fleet officer Robert Geary must face down a threat to the new colony of Glenlyon with half-decent weapons and volunteers.

Another addition on the list from Jack Campbell. His Vanguard novel is gripping. The characters he write relatable. And he wraps the narrative in a realism placed in a future universe. The outcome is a book hard to put down.

H.G. Wells - 1897
