Beware the Frozen Heart (Frozen fanfic)

When Anna is targeted by an evil filmmaker and pulled out of her little animated fantasy world, she discovers there's more to life than her sweet relationship with Kristoff and hugging snowmen. There are hardships and emotions and changes you don't want to face, and there are people standing in the way of your dreams. But at some point, you have to throw those things to the side and push through them. You can't let people walk all over you, and it's not as easy as three clicks and you're home. (Anna learned that the hard way.)
