Illuminae by Amie Kaufman and Jay Kristoff
This book is a bit of a roller coaster ride, but it was a ton of fun to read and probably one of the most imaginative books I've read in quite some time. The story is told in a series of memos, medical reports, interviews, journal entries, and text messages and focuses on two teenagers trying to survive after a corporation invades the planet of Kerenza. Kady and her ex-boyfriend, Ezra, manage to survive the invasion but are separated and live as refugees on two different space ships that are trying to flee from the mega-corporation's troops on board the Lincoln. Ezra is conscripted into the air force while on the military space ship Alexander, while Kady is a civilian living on the science vessel Hypatia and uses her knowledge of computers to hack into military files in an attempt to discover the reasons for the attack and find a way to help save both the Hypatia and Alexander from being destroyed.
I will be blunt: Illuminae is not a book for everyone and I had a difficult time getting hooked into the story. The story is very well written and contains a decent amount of snark and humor, but there is a lot going on and so many subplots that it can be a challenge to follow along. I do not read many novels written in an epistolary format and I found myself skimming certain sections of the book that were more factual or that focused on a subplot in which I wasn't as invested. However, this is a series that would likely translate well to film and I hope that this happens one day. I will likely read the next book in this series when it is released.
