2014: A great poem is read aloud and never heard again. For generations, people speculate about its message, but no copy has yet been found.

2119: The lowlands of the UK have been submerged by rising seas. Those who survive are haunted by the richness of the world that has been lost.

Tom Metcalfe, an academic at the University of the South Downs, part of Britain’s remaining island archipelagos, pores over the archives of that distant era, captivated by the freedoms and possibilities of human life at its zenith. When he stumbles across a clue that may lead to the lost poem, a story is revealed of entangled loves and a crime that destroy his assumptions about people he thought he knew intimately well.

What We Can Know - 5 Stars

Very well-written, entertaining and thought-provoking. I really enjoyed the focus on Tom, a scholar about 100 years in the dystopian future, who is researching a lost poem and also trying to teach uninterested students about our world. His appreciation of the past (our present) is fun to experience, and it provides a great perspective. For example: "I prefer teaching the post-2015 period, when social media were beginning to be drawn into the currency of private lives, when waves of fantastical or malevolent or silly rumours began to shape the nature not only of politics but of human understanding. Fascinating!"

And I loved a lot of the writing. There's a description of Tom trying to access a container and get it open, using not quite the right tools, and it reminded me of so many home projects I've done over the years. The effort, anticipation and frustration are captured perfectly.

Interesting premise but just ok

It was just really bland. Kind of poppy and readable in the way I needed to get out of a slump, and there were some elements of post-climate-disaster worldbuilding that were kinda cool. But I don't think I'd recommended it unless you enjoy British writers with their head up their own ass.
