Lightning

It only took one flash of lightning to change everything that Quinn knew.
Her whole life changed at that park. The naive 17 year old was a loud firecracker, but even the loud ones wouldn't know when to scream.
She was a smart one; straight A's, head of the Math club and captain of performing arts.
She had a normal life.
The key word being 'had'.
It was New Year's Eve when she got hit. She was nowhere where that party was. She decided that she would take a break from it all. The lights, the loud music, the stupid drunks that would approach her on her night out. She had enough of it all.
She took a walk out to the park next to her friend's house where the party was held. The storm wasn't forecasted. It was completely spontaneous. No one knew. No one knew that the rain would start to fall. No one knew that the thunder would boom. No one knew that the lightning would burst. Sadly, not even Quinn.
Skipping over exactly 2 years, Quinn finally wakes up from her coma in a hospital. No one was informed about her awakening. She was all alone.
