"You want to know what relativity is? It's when you fall in love with someone, and time speeds up whenever you're around them - a conversation is cut too short and a glance becomes too fleeting. Hours seem like seconds, and you can never get enough of their presence. It's also when time slows down whenever you're apart from each other - an afternoon of separation feels like days of absence. Seconds seem like hours, and time comes to a grinding halt. That, my friend, is the phenomenon of relativity." This is the story of how a normal girl saved a superhuman boy who saved a psychic girl who wanted to save the rotting world.

Runaways. That's what Lily and her best friend Will were. They had been planning their final run away since they were 13, and now at 16 they have finally set it into action. "We're not coming back." Will said like he meant it, like he could tell the furture. "The reason we ran away like this is to stay away." I looked up from starring at the floor of the train to look at Will. He looked wide-awake, he probably drank many cups of coffee before he came to get me. "What if we need to come back?" I asked. And it wasn't the first time I asked it. I asked back when we were 13. "Then we'll fight the urge. Why would we want to come back to this hell-hole? To be treated like we are worth nothing? To be sent to jail? We don't have much to loose." And his answer was the same, just as before.
