I'm partway through this part and decided I didn't want to wait any longer to provide you more feedback.
First, I am thoroughly enjoying this story. It had just enough of an A Plot to move the B plot along nicely. I love how you have captured Lois' thoughts and feelings.
Finally, you had expressed a hesitation about the story's title. I think it is fine as it is, but there was a phrase in part 5 that leaped out at me as a potential title: Snowbound in Smallville.
Now back to my regularly scheduled reading.
Joy,
Lynn
