Top of her class. First assignment. No way out.
Margaret McBride has earned her place among the Universe Corps' best. Selected for a coveted first mission aboard a communications array orbiting Earth, she and her fellow cadets are finally ready to prove themselves.
Then everything goes wrong.
When a hostile alien species known as the Lenotron launches a sudden attack, the station is thrown into chaos. Cut off from command and drifting above a planet they can't reach, Margaret and her team are no longer trainees-
They're the only line of defense.
Outmatched, outgunned, and running out of time, Margaret must lead her fellow cadets through a battle they were never prepared to fight.
Because this isn't training anymore.
This is war. And survival is no longer guaranteed.
