Illuminae, Paperback

The year is 2575, and two rival mega-corporations are at war over a planet that’s little more than an ice-covered speck at the edge of the universe. Too bad nobody thought to warn the people living on it. 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 one of the evacuating fleet, with an enemy warship in hot pursuit. But their problems are just getting started. A deadly plague has broken out and is mutating, with terrifying results; 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: the ex-boyfriend she swore she’d never speak to again!
