The last paragraph in this chapter signifies that she is starting a new life with joe and how she thinks that it is going to be better than it actually, that is signified by the sun-rising. and the fact that life isn't going to be as good as she thinks it will be, that is signified by the setting sun. 

it means that she is falling for the same think, when she married logan she thought that life would be better and she kept waiting for it to get better, it never did. she is now going through the same thing with joe.
