* The book title is slightly different. Perhaps it's "The Hidden King" or "King in Hiding." Searching for these variations might lead you to the right book.
* It's a lesser-known book. If it's a self-published work or a book in a niche genre, it might not be as readily available.
* You are thinking of a different work. Maybe you are thinking of a film, a play, or a song with a similar title.

* Do you remember the author's name?
* Do you recall any details about the book's plot or genre?
