WitchyKid is correct there is no way to physically travel to the universe set out in a book although depending on why you want to go there it may be possible to satisfy yourself through astral projection. On the astral plane it's possible to shape your surroundings based on your will and so it is possible that you could create a realm which mirrors the landscape and culture of the book (note however that the realm is not a physical place but an area of the astral plane/your own mind). Although you will not travel there per say it's possible for you to experience what it's like to be there although your physical body will remain in trance and not travel with you. Probably the best way to describe it for someone that is unfamiliar with astral projection would be the effects of an in depth lucid dream. If this is what interests you then I suggest you research astral projection and realm creation, I believe there are some other posts on realm creation here and there's certainly an abundance on astral projection.
