This morning, Kady thought breaking up with Ezra was the hardest thing she’d have to do. That was before her planet was invaded. Now with enemy fire raining down on them, Kady and Ezra—who are barely even talking to each other—are forced to fight their way onto the evacuating fleet with an enemy warship in hot pursuit.

But the warship is the least of their problems. A deadly plague has broken out. The fleet’s AI, which should be protecting them, may actually be their enemy, and nobody in charge will say what’s really going on. As Kady hacks into a tangled web of data to find the truth, it’s clear only one person can help her bring it all to light . . . and it’s the ex-boyfriend she swore she’d never speak to again.

Told through a fascinating dossier of hacked documents—including emails, schematics, military files, IMs, medical reports, interviews and more—Illuminae is the first book in a heart-stopping, high-octane trilogy about lives interrupted, the price of truth, and the courage of everyday heroes.
