Query: A disappointment from a favorite author

Margaret Atwood is a cut above the rest. "The Handmaid's Tale" and "Alias Grace" were unique and gripping works of fiction with characteristic traces of Atwood's element of science fiction/fantasy. This book, however, was very disappointing. It ambled on and on, and although Atwood shows off her exceptional talent through a diverse range of character portrayal, the plot left much to be desired. Don't bother.
