There are many reasons someone might gravitate towards a book. Take a debut mystery, for example. A reader might pick it up because they are a die-hard fan of the genre. They check out any new mystery title recommended by their favorite BookTokkers. There are readers who gravitate towards a book because of its themes, or because the characters look, speak, or behave like they do. Then there are the readers we have yet to discover, who didn’t expect to fall in love with a title and can become the book’s greatest evangelists.
