Here are some titles I'm thinking of:
Lies of Winter's Life
Lies They Told
Sky is Over
The Sky is Falling
Darkest Before the Dawn
Winter's Darkest Fears
Which one is the least bad? And do you think the having the word "Winter" in the title is too cheesy. Three of the main characters have the last name Winter.
EDIT: Came up with the title. It's going to be "Fears of Winter"
