In his dystopian new novel, The Wall, John Lanchester imagines what might happen if we built a wall around the UK coastline to keep ‘the Others’ out.

Beaches no longer exist and the sea can only be viewed from high ground, but everyone’s safe – in theory. Are the Others really that different to us? John explores where the generational divide over climate departure and immigration might lead, and whether it’s a world we really want to live in.

John is the author of five non-fiction books, including Whoops! Why Everyone Owes Everyone and No One Can Pay and five novels, including Capital which became a BBC TV series.
