Query: not really sure

i purchased this book from a yard sale and havent quite finished it yet , i'm only on page 90 or so and really dont understand what its about maybe i'm crazy or something , but i'll keep going and will come back later for a better review for you and possibly a better opinion of it, however i am glad that i only paid 50 cents for the book as it does not hold my attention for longer than about 1 or 2 chapters at a time thank you
