Should We Stay or Should We Go

This is the first Lionel Shriver I've read and I'm instantly in love with her dialogue. Kay and Cyril feel so real, she brings them off the page and into my lounge. Through good and bad, sickness and health, their marriage feels very real and Shriver excels at the nuances of the human experience. However the book overall feels a bit of a slog, and the gimmick of ‘sliding doors' wore a bit after the 7th or 8th iteration.
Tackling events ranging from Brexit to Covid, the refugee crisis, the financial crises, elder abuse and climate change, Should We Stay or Should We Go is a sweeping yet intimate novel of two people who take charge of their fate. 3.5 stars rounded up for the gorgeous writing.

On one hand, it's always comforting to read such elaborate prose with the right choice of words and impeccable editing as Shriver's books always have. On the other hand, it's bizarre, a bit too bitter and political, and Kay and Cyril are not that interesting as to have their multiple destinies followed.
That said, it rang home because apparently im already at an age when this topic made sense to think about. Sigh.
