For the answer to the question above, I agree with the quotation. Literature should not be all about sound facts nor is it about fantasies. It must lie in between. We each have our own levels of understanding and our own personal fantasies. A work of literature must provide us with something new in order for the time spent in consuming it be worthwhile. The Book Thief tells us of hard facts but it also provides us with something else, how a life of young child harboring a wanted man is changed after the fact. In the Lord of the Rings, a fantasy world is so vivid and wide that you yourself can navigate through it.
I would say the best word that has the most similar meaning to wary is "fear".
A 12-year-old boy named Tom Sawyer who resides in the imaginary and fictitious town of St. Petersburg, Missouri. Tom had 2 best friends named; Joe Harper and Huckleberry Finn and had a short-lived admiration with his classmate Becky Thatcher that is apparently as he tries to fascinate her with his handsome looks, boldness, and strength. Tom’s parent is already dead that’s why his only relative left is Aunt Sally Phelps.This imaginary character's name may have been consequential from a cheerful and vivacious fireman named Tom Sawyer.
