The rest of the team is holed up in Hell, and it's been a week since Kevin heroically drove off into the night with Corrie. It's during this week that Ellie's written the book we've just read.
No one knows Kevin and Corrie's fates, but they all hope for the best and take comfort in the fact that the military hasn't shown up in Hell. In the meantime, they're keeping busy with plans and making a home for themselves in the woods.
Ellie is keeping her hope up that people are good instead evil, and she hopes she and her fellow Hell-dwellers can stick together and survive the war.
