Illuminae

I quite enjoyed this genre-crosser of a story. The format is a little odd in that the entire story is told through a series of hacked and intercepted documents of various kinds. But, it works. The main character is Kady, a 17/18 year-old girl. Her love interest, Ezra, is another important character and a total bad-ass. Though young, Kady is very smart and very tough – which she has to be, because this story really puts her and everyone else through the wringer. I hesitated to call this YA because it is so violent. But, with the teenage main characters what else can it be?
In addition to the romance elements (which actually don't get very sweaty as Kady and Ezra get very little time together), we get space battles, an insane computer (or is it?), a plague that turns people into zombies, and lots of action. The pace never lets up.
I wanted to give this book five stars but finally couldn't because of something toward the end of the story (sorry, can't tell as that would definitely spoil the book). So, 4.5 stars.
The audiobook was a very well done multi-voiced performance.
