The plot really ebbed and flowed in this book, it seems that the big chunk of it that's really important are the flashbacks that occur throughout the whole book.
The main plot seems to stagger from a calming assuring thing to something that's almost unbelievable in the story itself.
There are a lot of twists and turns.
The characters themselves are almost hard to describe because of the way the story goes. The main character seems to float more in the middle of being and not which makes it hard to really understand him.
There are parts of the story that had me scratching my head from the math they were throwing around but other times it was clear. It was obvious what he was going through but not always obvious why he chooses what he does next.
I'm not positive about how I feel about this book but I don't regret reading it.
To be honest, though, everytime the main character called his wife kiddo I was thrown so far out of the story that I almost gave up reading it
