Illuminae is a fantastic story told through unconventional means. The reader acts as an observer as data files, briefing notes, transcripts, and surveillance summaries tell the tale of Kady Grant. The plot was gripping, the "chapters" were short which made this very long book (shy of 600 pages) fly by, and the characters were very easy to get invested into. I don't tend to read or enjoy sci-fi but this book was absolutely incredible and I will be picking up books two and three off my shelf and giving them a read as well!
