Query: This was two books -- one good and one bad

I've enjoyed other books by this author but I thought much of Fault Lines was a waste of time. It was as though she had ideas for two books and thought she could get away with combining them. The story line about her mother-in-law, daughter, husband and sister was warm, funny and moving (book one). But she interrupted the story with (book two) a melodramatic, romance-novel, Bridges-of-Madison-County interlude that inspired me to roll my eyes and flip pages until I could find a plot again. The only reason I bothered to finish the story was because I cared about the original characters. If you like romance novels, you'll love this book. Otherwise, don't invest the time in it (or just skip the pages with the romance in it -- you won't miss much.)
