Ian McEwan, always a class act

Set in two centuries, partly around 2014 and then in 2119 when what happened has happened, climate change and a catastrophic tsunami drown much of the UK and Europe. Basically a love story set in academia, a famous poet writes a poem for his wife, he reads it out at her birthday and she receives the only copy which is then lost. So come 2119 an academic is searching for the lost poem and McEwan treats us to a twist in the tale. Thus the story is about our destroyed world and also a love story and a mystery. He leaves us to our own imagination - perhaps the most powerful way to get across what is happening to our world. I would have loved more detail but this is not a literal account but an elegiac story from a writer with a great command of ideas and language.
