I am a big fan of Becky Bloomwood. I loved her first three books, Shopaholic, Manhattan, and Ties the Knot. However, this book was not as good as those. I am, sadly to say, starting to get a little annoyed at Becky. Does she ever learn her lesson? Her and I are the same age, yet she continually repeats the same offenses and covers them up with lies. Why Luke stands by her is beyond me, which only perpetuates her childish behavior. Like I said, I enjoyed her first three adventures, but with Sister, I feel that Kinsella only wrote it to continue the series without coming up with anything really fresh and new.
