Train Hoppers

Train hopping is dangerous and no one knows this quite like Cleo and Andrew. They can't help it though, travelling is in their blood and a knife in the gut or a few stolen goods aren't going to stop what has been past along from generation to generation. When fate decides to step in, however, and hurt the two in ways they could never have imagined, can they go back to their disruptive life on the tracks or will things be forever changed?
