MACY HENDERSON is a troubled and intelligent teenager who lives in a run-down, one-room motel with her ill mom. Macy's friend, KATE, invites Macy and her two friends, KHLOE and RYAN, to a sleepover to meet Kate's new friend, ACE.  As the night goes on, Macy realizes that there's something wrong with Kate's new friend but keeps her emotions to herself. Khloe proposes a plan to get Macy and her friends to try a potion she cooked at home, claiming that the magic from her spell will open doors to new opportunities and reveal the truth of life.  When Macy wakes up, she learns she doesn't remember the last three days. It was Thursday when she fell asleep on Kate's chair, but now it is Monday morning, and she missed States for Tack and Field and cannot face her crush, DEAN JOHNSON.  Macy attempts to retrieve answers about her missing time from Kate, but Macy knows that there is something wrong with her. Ace gives Macy a necklace with a precious Amethyst, claiming it will yield her bad dreams. Macy goes to school to retrace her last steps, but something makes sense once she talks to Dean. He promises her that together, they will get to the truth.  Macy discovers Ace is abusing Kate, but Kate lies to her. So, Macy, Khloe, and Ryan develop a plan to trap Ace and reveal who he is. The plan seems simple: get a drone through Kate's window, look, and get out, but they discover horror. Kate's body is artificial and appears to be under Ace's command.  Macy tries to run Ace down with her car, but a supernatural force totals her car with Macy, Khloe, and Ryan inside. Dean shows up to get everybody to safety, but as he tries to get to Macy, Ace gets to her first and takes her to a hidden location in an abandoned house.  Macy is a prisoner. An invisible power chains her to a chair and forces her to learn Ace's true identity: AZRAEL. He is the Angel of Death who came to Earth to find Macy because she is born of a powerful evil that will end human civilization and allow Hell to make a comeback against Heaven.  Azrael makes Macy choose between sacrificing her soul or Kate's life. When Macy decides, she realizes Azrael lied; Kate is already dead. As Azrael sucks the life form from Macy's body, a brighter light enters the old, beaten-down house and fights Azrael until a dark and light orb dances around the home, fighting one another, and they both leave Macy.  Macy wakes up and ventures barefoot and half-naked to her motel strip to find her mother dead and feels the changes inside her body from the MARK of the BEAST.  Now, Macy must learn the truths of her identity while fighting Azrael and his demonic blood racing through her veins. She must choose to live as a half-human, half-demon on Earth and help keep humanity alive when Azrael and the artifacts he unleashed onto the Earth force her to end it.  In a battle between good and evil, Macy must love her human self and her demonic self if Earth is to survive. With the help of a powerful witch, Khloe, a fallen angel, Dean and a human, Ryan, Macy continues to fight for humanity even though she was born to be the REVELATIONS Monster. She is the key to unlocking Hell and unleashing the Devil into the world, but she must refuse the evil powers, no matter how hard life gets.
