How to get out of reading a book?

My good friend wants me to “borrow” his copy of a book. He says that he really wants me to read it. I am not at all interested in reading this book. I am a very visual thinker, not a reader; I do not enjoy it. Apart from not enjoying reading for leisure, I am in no way interested in the book’s topic. Additionally the writing style is annoying. For me to not read the book, it may be offensive to my friend. And I do not want to be dishonest. How should I handle this? and please do not say “just read the book”.
