A review by abookishpenguin
The Darkness Outside Us by Eliot Schrefer

4.0

Ambrose and Kodiak are alone on a joint space-faring mission, run jointly between the last countries on Earth. Neither can remember the launch, only their mission: to reach Titan and rescue Ambrose's sister. The more they learn about the ship and the future, the more dangerous their situation becomes. 

It's going to be hard to write a review without giving away spoilers. This book was great. 
On the surface, it looked like this would be a cute teen romance set in space. It certainly was a teen romance in space, but it was so much more than that. It was a story of survival against all odds, of hope and of love. 
I struggled to get into it at first. It was narrated in the first person by Ambrose, who knew very little about the situation. The reader learned as Ambrose did to start with, and that made the start feel a bit slow to me. But once the twist hit, and this turned into more of a thriller, I was hooked. 
This book has really only got two characters and an AI, and it needed these characters to be well developed and interesting. They were - they both grew as the story progressed, and had a lot of depth. 
This was a great, cross genre adventure, blending sci-fi, romance and thriller into one really good read.
