Critique on The Snow Child

I finished reading The Snow Child (yes its based off the fairy tale). It was really good -I recommend it. 4 and a half stars. The only thing I thought kind of irksome was how that sweet little, feral girl turns into this (SPOILERS!) pregnant teenager. That's the way it is though, isn't it. We all are forced to grow up in the end. I also kind of wished that she really was (SPOILERS AGAIN!) a child formed from snow and wishes. But those are not legitimate complaints. Read this, its kind of fantastic and very magical.
