The Last Ones Standing

A little girl named Hope, who died three hundred years ago, lives with her three siblings in a floating house. She has a Guardian, a mythical being that has the duty to protect her at all costs. One day, Hope's oldest brother, Sawyer, decides to do a survival game with mortals because he is bored. In this game, the participants will have to kill Hope and her siblings, so they can have the chance to bring a loved one back to life. However, Hope realizes that playing with human lives is wrong, so she decides to help the participants win the game, even if that means that she will have to die.
