It's Always the Quiet Ones

Macy was your average quiet girl, with zero luck in life. However, when she finds a notebook that obeys her every command, the tables turn, making it so she can control not only her life but everyone else's. She rises to power, having everything, all powerful, all knowing, a human god, unconquerable, but as time goes on she begins to realize something, that leads to her destruction but at the same time her relief.
