Don't worry, I won't ruin the ending for you. It was particularly frustrating, because the twist at the end is GOOD, really good. Emily has read the novel and absolutely loves it, it has become her new favourite and is being encouraged to all her friends. I've now started reading the novel and I am loving it, but must admit, knowing how it ends makes me look at some of the characters differently.
I also read Agatha Christie and through blogs, uncovered the murderer behind The Murder of Roger Akroyd before getting a chance to read it. Another great twist I won't get to enjoy through the experience of reading. Have you had an ending spoilt for you? Maybe while you were reading a novel? Can you still push on and read it?
