The Buried Giant: Kazuo Ishiguro

I didn't like how this book ended, I like to make my own interpretation, but if this didn't end happily (I don't interpret it as doing so)the book seemed pointless to read. The story follows a Briton couple who are having problems with their memory. They decide to visit their son whom they haven't seen in years and prepare for the journey. Along the way they meet up with a Saxon warrior and a Saxon boy who had been bit by dragon. The Warrior has a secret plan to find and slay the dragon. They meet up with Sir Gawain who we find out at the end of the book is the dragon's protector. The warrior and Sir Gawain fight to the Gawain and the dragon's death. The old couple finally gets to the ferryman what they believe to be the final leg of their destination, then their memory returns. Here the dragon was responsible for the mist that had settled on people's minds. The couple remembers that their son had actually died from disease and that the wife had been unfaithful. The Ferryman is to judge if they can both be carried across to the island and asked them both questions. He tells the husband he will take the wife first and come back for the him. The wife thinks everything will be ok, but the husband knows if his wife goes without him, he will never see her again. The boatman starts the journey with the wife while the man wades out to see. The book ends. I took the island to be "death" and that the man would swim there rather than stay alive without his wife.
