Infinite Game: Her Return Is the End

The Old Bookworm Is in the Boredom Stage and Always Stops Reading Halfway Through the Book.

I'm looking for a book that's long-lasting, has good writing, and can keep me reading; it can be anything from cultivating immortals, traveling through time, fantasy, etc. The subject matter is not limited, as long as it's good-looking. Please, my child is out of books.
