SBR: There can be no doubt about the quality of writing given the Margaret Atwood’s reputation. But The Blind Assassin leads to nothing and is still super-long. So, it’s difficult to justify the time it takes to read the book. The suspense, which is the meat of the story, is manipulated, not natural at all. You feel cheated in the end.
To read or not to read: This is the only book by the author that I have read (decided to start with the Man Booker Prize winner!). But my guess is that I would have been better off reading something else. So would you, I think, unless you are a fan and want to read all of her books. In which case, go ahead!
