How we scored them

Scores run from 9.2 to 9.8: each book’s point total is placed on that range, so more points always means a higher score. Reading age or level counts on a list where at least one listing gives one, and a book whose listing gives none then scores zero on it. Where no listing gives one, the score is taken over the other 85 points. Books carry no warranty, so warranty is not scored.

How to choose the best sci fi military books

Series length matters

Grimm’s War runs 10 books and the Kurgan War 9; the others are trilogies. Long series reward commitment, trilogies finish fast. Pick the runway that fits your reading habit. Also see our fantasy lists for more.

Fleet, squad or street

Naval fleet action (Against All Odds), colony defense (First Strike), misfit crews (Unlawful Orders, Shattered Starship) or near-future ground war (Hot Solar). The subgenre sets the feel more than anything else.

Mind the book number

Four picks are book 1; Hot Solar is book 2 of 3, so start with Cold Solar there.

Before you buy

• Confirm the series order; one pick is book 2.
• Check the tone: fleet procedural versus gritty versus comedic.
• Match the series length to your appetite.
