Divided

This is a prequel and not required listening, but can be listened to before or after book one. Three best friends. Three lives that are about to change drastically. As high school juniors, three best friends must start thinking about their future - even if it means that they will have to fight in the war instead of starting their careers. Riots and ambushes become more common. And when sickness rips through the communities, the friends will be separated by forced podding quarantines, and Deja will learn the hard way who she can trust. But tragedy is about to strike close to home. Nowhere offers refuge anymore, and the three friends realize holding on to their innocence is impossible. Who will be left to pick up the pieces of their friendship once the newest outbreak is over?
