The book was published
I've got a hard copy of the book, and I've read through part of it. Personally, while the book has an important message that needs to disseminated, I don't think Gook is particularly well written. People should indeed know about McCain's racism... I just don't think you needed this entire book to do it. Perhaps a solid, extended essay would've been just as effective.
But a book gets people talking, and helps draw attention to the issue. It's certainly intriguing, and there's definitely a lot of information in there that'll make you think twiceas an Asian American, a person of color, or any kind of minorityabout wanting John McCain as President of the United States.
