"Haven" actress Emily Rose finds maintaining her balance with the Syfy show's twists and turns to be a spellbinding challenge.

During the closing moments of the Season 1 finale, Rose's character, FBI agent Audrey Parker, discovered that she was in fact not the real Audrey Parker. Even her job in the FBI was fictitious.

"I remember I did what I did with the [script] when I first read it, I threw it across the room and I was like, 'Oh, no. Oh, no. What does this mean?'" Rose said in an interview with reporters that included Rabid Doll. "And I called my writer up right away and we were talking and I just was really confused … I went through a lot of the emotions that Audrey went through.

"So, I had a pretty strong reaction, but then I was just really thankful that they did not tell me until later because it kind of allowed me to really have that experience."

Based loosely on Stephen King's novella "The Colorado Kid," "Haven" follows Audrey's investigations in a small Maine town where a substantial number of residents possess supernatural abilities. As her investigation progresses, she teams with local cop Nathan Wuornos (Lucas Bryant) and soon discovers shocking secrets about her own life.

As Season 2 opens, the series will follow Audrey as she explores "what this means if she’s not who she thought she was," Rose said. "And then, we’re also going to go head long into looking into each of the troubles of the week and more into the town of Haven and where this all comes from."

Coming to grips with just who Audrey is became a tricky concept for Rose to navigate as an actress.

"It’s kind of scary," she said. "I mean, as an actor you are kind of given this past and its history that you understand. … And I think in the situation with Audrey where there are so many unknowns where I don’t know, it’s like they pulled the rug out from underneath me.

"So, it was a really interesting acting exercise … in terms of the anxiousness and the nervousness of not knowing what to do or what to do next. I just had to trust that Audrey was most likely feeling those same exact feelings; so I needed to do was to fall into my work and to fall into the text and try to tell the story well.

"The writers have a very clear vision, in terms of what the last scene of the entire series will be, and so they’re always working towards that point."

Season 2 of "Haven" premieres July 15 at 10 p.m. ET.

The series has several cast additions for Season 2, including Cristián de la Fuente ("Basic," "Driven"), WWE superstar Edge, Vinessa Antoine ("Being Erica," "Soul Food") and Jason Priestly ("Tru Calling," "Beverly Hills, 90210"). Priestly will guest star in four episodes and direct one.

"Haven" is produced by Entertainment One in association with Shawn Piller, Lloyd Segan and showrunner Scott Shepherd ("Tru Calling," "The Dead Zone").
