The cover and description of this book did not prepare me well for what the actual story would be like. The secrets that the ship was hiding and that the Ambrose and Kodiak slowly work out made it hard to put the book down.  The love between the two was desperate and tender in such a sweet way. This book was a lot darker and more existential than expected and that was a really pleasant surprise. 

also the author's use of time and how he calculated it out was very clever.
