Illuminae by Amie Kaufman and Jay Kristoff
Breaking up was hard enough for Kady and Ezra. Then their planet got bombed by a hostile corporation.
Rescued by separate ships, Kady and Ezra stay in touch, kinda. But when one of the other rescue ships is destroyed by the rescue ship Ezra is on, there is clearly a problem, and it's possible that only Kady can solve it.
A crazed artificial intelligence that makes HAL 9000 look like a Teletubby. A virus that is turning some of the survivors (and some of the crew) into zombies. And that hostile corporation ship still in pursuit.
What could possibly go wrong?
This isn't the greatest book I've read this year, but it's certainly the don't-put-downablest book I've read in a long time. The audiobook is produced with a full cast, and perfectly captures the suspense.
No sex (a few vague references to "the time we..." but no details). LOTS of violence and blood and gore (zombies!). All the swear words are bleeped, even in the audiobook. As the introduction to the book says, "...the story kicks off with the deaths of thousands of people, but god forbid there be cussing in it..."
Recommended for ages 12 to adult. The story may be too intense for young or sensitive readers.
