Glad you finished it. I was reading.on a Kindle while backpacking. As soon as I got to where Rocky said he couldn't sleep alone, I started crying (guessing why, as it would be another few pages before it revealed the reason). I had to stop reading there, not because of dislike, but because I could not read this on my own... it was too good.

As soon as I was off the trail, I got the audio book and listened to it with my wife.

I liked the science, and never glazed over (PhD in Physics), but my wife did. I don't think it's that you didn't get it. It might just be that it was boring if you don't innately find this topic interesting. But, the Rocky-Grace relationship was so fantastic. Amaze, amaze, amaze jazz hands

My only part that I found I disliked was the rapidness of creating meaningful communication. But, I am able to look past that as the rest is so good.
