Natural Or Supernatural

Pippie Delaney is a smart, friendly, talented young girl we had just convinced her mum to let her go away to Australia with her friends Millie, Liam and of curse, Cory, her boyfriend. But they seem to get into allot of trouble among the way, do they make it to their destination or does tragedy win... Also did I mention that, despite being a normal teenager who wants to get away with her friends, it also just happens to be a very special girls birthday that same day.
four friends, two worlds, one story. the only question is, who will survive???
