There may or may not be. Some books are named after characters, like 'Robert's Adventure', in which case there would be a story about Robert in that book. But in a general collection of books, it's a matter of chance. There are so many books out there, some with Roberts as main characters, some as side characters, and some with no Roberts at all. So we can't be certain just from the words 'robert book story'.
Well, it depends on the genre of books you are looking at. If it's a fictional story, there might be a Robert who is the hero or a key figure in the plot. For example, in some mystery novels, a Robert could be the detective solving the case. In a historical fiction, he could be a person living in a particular era and his story could be about his life during that time. However, without more specific information, it's hard to say for sure if there is a particular 'Robert book story'.
