Crossing Universes (NaNoWriMo13)

An ordinary 14-year-old girl, Violet, plays truth or dare with her friends and is dared to go through the forest behind her backyard. She gets lost and finds a sort of gate that leads to a world full of monsters and creatures and falls through, fainting at when knights and warriors come. She wakes back up in a castle dungeon and is soon let out when she tells the king who she is and is deemed trustworthy. As she overhears a conversation that a war has been declared and that the evil king has declared war for power and land, Violet says that she'll go over and try to defeat the evil king, just so she can earn peoples' trust. The king agrees, thinking it as a good idea. Now, she must defeat the evil king and find her way back home.
