I’m surprised only one other comment mentions Harry Potter, which is definitely my answer. I was part of that “Harry Potter” generation that was right around his “age.” Those books really were incredible for spurring reading in children, and they definitely stimulated my imagination more than many activities in my childhood. Reading them now is comforting not because of the content of the book, but because of the feelings of nostalgia for and positive associations with my childhood that come with it.
