I have to say that I was not too sure as to where this book was going, but what a surprise!
I don't normally pick up sci-fi books, just because a lot of sci-fi that populates whenever I look for recommendations is not accessible for me. By this I mean that many of the terms and science go over my head or are really complicated for me to understand. I'm not a math or science person by any means. That being said, this book's science fiction elements were so accessible for me. I was able to fully understand what was happening, and able to build everything in my head.
Not to mention the "double narrative" aspect this book has is so well done. It left me guessing as to who was commenting on what we were reading, and why they were making the connections they were making. It's kind of hard to explain, but this book runs on a rescue-esque type mission alongside a spurned lover. On the right pages of the book is the mission and the main science fiction elements, while on the left pages of the book are the footnotes left by someone who is commenting on the story as the reader goes along. This was so well crafted, and I was itching to find out who was reading this with me, essentially.
There were typos, and sentences that were accidentally doubled up on, but other than that, the writing is awesome. It builds suspense, and lunges at you with scientific horror.
I recommend this book to anybody who is a fan of Alien - and its subsequent sequels/prequels - and Into the Drowning Deep by Mira Grant, and possibly The Deep by Nick Cutter. In my opinion, this was a better Into the Drowning Deep, just with its own spin on it.
