In a world submerged by rising seas, can the secrets of the past be discovered?

A great poem is read aloud and never heard again.

For generations, people speculate about its message.

2119: With the UK’s lowlands submerged by rising seas, those who survive are haunted by all that has been lost. Tom Metcalfe, a university scholar, pores over the archives of the early twenty-first century.

When he stumbles across a clue that may lead to the lost poem, he reveals a story of entangled love and a brutal crime that challenges everything he thought he knew about the past.
