This morning, Kady thought breaking up with Ezra was the hardest thing she’d have to do. This afternoon, her planet was invaded.

The year is 2575, and two rival mega-corporations are at war over a planet that’s little more than a speck at the edge of the universe. Now with enemy fire raining down on them, Kady and Ezra — who are barely even talking to each other—are forced to evacuate with a hostile warship in hot pursuit.

But their problems are just getting started. A plague has broken out and is mutating with terrifying results; the fleet’s AI may actually be their enemy; and nobody in charge will say what’s really going on. As Kady hacks into a web of data to find the truth, it’s clear the only person who can help her is the ex-boyfriend she swore she’d never speak to again.

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