Imagine waking up in a room, having no idea where you are, or what has happened for the last three years of your life, because apparently you have been in a coma for that time. You then find out that the apocalypse happened during that time and that it is your job to repopulate the world. Well welcome to Mason's new life. What will happen when he finds out that his little sister isn't as "little" anymore? How will he take care of himself and her with no parents? And what will he do about these feelings growing for this girl he just met?
