The beginning put me off a bit--when they are killing all the people to claim the planet, and Fourteen's sudden change in behaviour...but fast forward to him landing at the new location and meeting Connell and I liked it.
It might have been Fourteen's learning to speak out loud after all the conversation being done mentally or his protectiveness of the baby, but he really grew on me.
I thought the relationship between him and Connell was really cute, especially the:
"Why do they do that with their lips?"
You'll know what I'm talking about when you get there.
However I'm not sure if I liked the end with the aging of the characters, especially with how short it is. I know it had to end somehow but I wasn't a fan.
