At the center of this madness is teenager Alex and his two young sisters, thoughtful Briana, and feisty Julie. Their parents are missing, and the siblings must decide to either wait and believe their parents are alive and come back for them, or imagine life on their own, in a deadly wasteland. And resources are getting low, the weather is changing, and their situation is getting worse.
I enjoyed the Morales family, what a contrast to Miranda's family in Life as We Knew It. It seemed Pfeffer wrote this companion in response to all the outcries of spirituality and morals that seemed so lacking in the first book. While you still need to suspend disbelief (seriously, couldn't the scientists predict something like this could happen?) Alex's situation was much more dire, and even with his faith, and the help of his church, there was no quick thinking mother to stockpile food and other items for him, he was on his own and he had two sisters depending on him. His courage was genuine, and you pray for him and his sister to triumph.
