Rewind by Amelia Rockwell

She was only supposed to be travelling to the past for a very short while, but instead, seven minutes turns into seven days.
Suzannah Jack finds herself trapped in 1987, thirty years in the past, with only the clothes on her back, but she doesn’t find herself alone. Matthew Ivey is a researcher whose future is foggy at best. She knows she shouldn’t get involved with a man with whom she cannot hope to have a future, but her heart has other ideas. Will she listen?
