Ponykind is under attack, but not by the usual threats that stem from magic. Aliens known as buggers have come down in an attempt to colonize Equus. Celestia herself managed to defeat their colonization force, dying a hero and a martyr. Luna has picked up the rule in her stead, and pressed Equestrian technology to its limits, while also starting campaigns to select capable commanders for when the next invasion comes.

100 years later, enter Twilight Sparkle. Brilliant, strategic, and anti-social, she has the ability to take command of Equestria's largest fighting force. And she’s only six years old.

This is an alternate universe set in “Ender’s Game” by Orson Scott Card.

The first few chapters will be rather similar to those in the book, but I expect it to diverge after I get into the thick of things.
