The Butterfly Effect / / Harry Styles

One night, Felicity Evans was awoken in her sleep by a teenage girl who asked to be named Fate. She was told that she had to go back in time in order to prevent herself and another special person from beginning what could only be the start of a new, even more, destroyed society than the one we're all living in now.

There are a few catches. Felicity has no idea where in time she's going, nor does she know what exactly she needs to succeed during her week in the past. She will have no memories of what led her to that moment in time, and they will only come back to her near the end of the week.

Throw in Harry Styles, Felicity's so-called future husband and favorite music artist, though she doesn't remember that anymore. He's only a sixteen-year-old boy competing on a singing show who kindly offered her a place to stay.
