Corona Theatre School. She turned her back on a dream summer cruise with her family on the Queen Mary to film the 13 episodes.
"We filmed all through the summer and it was hard work and a real eye-opening experience for me. To be on a real set and see how it all worked was really interesting.
"It was nerve-wracking at first because it was my first real TV role and I had a lot of lines to learn. But the crew were brilliant and really helped us feel at home. It was like one big family and I don't think I have ever had as much fun.
"The producers were really happy with the way it came out and they have spoken about a second series. We just have to wait and see how the ratings go."
