The Beginning

So mum and I are always moving houses because of an excuse she uses everytime. So we live in a new country now but on the first night I stay there I see a weird creature? It attacks me and I get rescued by a hot stranger who somehow killed the thing with what looked like to a ordinary crossbow? But it wasn't he actually used his so called powers he says he has? And says I'm something that's more than human. What's going to happen next
