Query: Dissapointing

I think any woman with a sister would be attracted to a book that promised an intelligent perspective on the "smart versus pretty" issue. I think the author is right when the says that all sisters have their own views on which is which. However, after promising such a satsifying subject, the book wanders off into a poorly written tangle of weird and implausible plot twists and vivid descriptions of what everyone is wearing. If the book had billed itself from the start as a cotton-candy mystery, I might not have been so dissapointed, but as it was I could barely bring myself to finish it.
