The Crescent Moon

Hope and her friends (Vance, Rose, and Zach) are up against the world with changing personality. When a crescent moon comes out everyone's personality changes, Hope on the other hand doesn't get affected by the moon and it's power because of a necklace. She is being challenged by the moon to get through the night without using her powers or harming her friends.

Would Hope be able to complete the challenge? What is Hope hiding? Will her friends find out about her powers?
