How Did I Get Here?

Miranda Wilter was a normal girl living a normal life, until one day she accidently won a sweepstake for a free cruise to Paris!
She thought that her free vacation would be like heaven, until she got on the ship and learnt that it was filled with rich people, making her feel like a piece of trash.
One day a terrible storm brewed, causing the ship to crash into an unknown island! She, her friend Lucile, a beauty obsessed woman and a sphinx cat are the only survivors.
When they go venture into the island they find out that the island is inhabited by a village of people who seem to think its the medieval times!
What is going on here, why do these people think its the medieval times? Are the storys of a rose witch and headless horseman in the village true? Will they ever escape?
