Speeding Hearts (Bart x Reader)

Meet (Y/N). A smart, strong, and beautiful girl. She tries her hardest in everything she does in order to make her older sister, Zatanna, proud. That's right. (Y/N) is the younger sister of the great magician. She knows the same spells and is even part of the Young Justice league. Everything in her life seems normal. Except, a certain unknown energy impulse.

Meet Bart Allen. Speedster and grandson of Barry Allen aka Flash. When this speedster comes to the past for an unknown mission the world is flipped. He thought it would be easy. He would save the past then return home. Except, his time machine breaks and a certain young magician appears before him.

How will these two lives change? Will it be for the better or for the worse? And what is (Y/N) hiding that not even Batman can figure out?
