input:  Now, answer this question: Title: Painfully Boring Review: I have to say that this book came highly recommended by some ladies in my knitting group. For me it was a painful read. The dialogue was simplistic and the plot was predictable. Macomber's characters are lame and outdated. I do not recommend this book for anyone who wishes to be challenged intellectually or emotionally. I gave it one star only because there is a knitting pattern in the book.
