This book was amazing. I loved the style of writing, and seeing Ryland working out issues. My favourite POV is first person, and feeling like you're in their head. I loved how much science was in this, and although I definitely didn't understand it all, I enjoyed reading it and was impressed how Weir would've had to keep it all straight to be able to explain it right.
I went into this book mainly blind, I knew that it was about a man waking up on a rocket in space and having no memory. So there were quite a few twists that I really enjoyed discovering. You really can't say anything else about this book without spoiling it. So I'll leave it here with, I loved this book and I really enjoyed reading it.
