The ending I would change.  I would have Gabe grow up Joans would be a man  in my ending. I would do this because I find it unrealistic for a 12 year old and a baby to survie the heat hunnger and snow all at once.I also think that the giver could have put a car out there with directions on where to go.the ending in my way would also include Joans And Gabe coming to find Society with a little more desicption the ending said Joans just knew I would have him see it and talk about it.Gabe would also be grown up a little like 10 he would have the memories that Joans have and he would say to Joans say we made it.
