How much longer until like, you know, the end of forever?

In just 13 days, George would have turned 18. He would've been able to drink. He would've been able to.. i don't know, buy fireworks. He would've been able to open a bank account under his own name. But unfortunately, George wouldn't be doing any of those things. Because 13 days before George would have turned 18, he died. And life as a ghost has proven quite boring. Until he comes across a certain boy who he holds a strange fascination with.
