The book 'The Girl Next Door' is a true story. This means that the events, characters, and situations within the book are rooted in reality. By being a true story, it has the power to evoke strong emotions in the readers because it reflects real - life situations. It might deal with various aspects such as relationships, personal growth, or challenges faced in a particular environment, all of which are based on actual events.
Perhaps the story is about her facing difficult circumstances and emerging stronger. Or it could be a story of love and sacrifice that changed her life forever.
I'm not entirely sure specifically as it could refer to different things. It might be about a real - life story of a girl who was someone's neighbor in 2007. Maybe it involves her experiences, relationships, or some events that took place in that year.
