This is odd because genre usually comes naturally with the first few characters but not this time. I have two characters and I know a lot about them except their era/genre. They are brothers, named Tony and Shaun Bradford, somewhere in their twenties, and all I know it's not historical, so either contemporary or in the future - but I don't know the genre. They have been through a lot and their world is definitely not a nice one. All the family they have left is each other. So, any ideas what would fit them?
