There are three books by King that I felt were soft balls that barely made it over the plate. Rose Madder, From A Buick 8, and The Girl Who Loved Tom Gordon. I agree with King's assessment of this book. To me, it felt forced and you can almost feel King searching for the next word. As a reader, I felt lost and bewildered. Many say they didn't like the supernatural element of this book, but to me that's the only thing that saved it. It felt formulaic (Abused Woman pursued by Predator) and the odd and whimsical world Rosie enters redeemed the story, I feel. Slightly elevates it. The reader knows what will happen (more or less) when she buys the painting, and is just waiting for it to happen. Luckily for us, King's worst day at the ballgame is still extraordinary.
I will eventually read it again. Maybe, the second go round will make a difference as some of you have noted. Don't stone me.
