I've been completely engrossed in The Underground Railroad, this year's Pulitzer prize-winner and one of President Obama's choices for last year's summer holiday reading. (If we were treated to President Trump's booklist, guess I must have missed it.)
It's devastating and wildly inventive, an imagined history of slavery in the southern states of America and as I came to it fresh - don't google it or read the reviews - I was quite a way in before I thought, 'Hang on ...'
Anything I could write feels like a spoiler. But even allowing for a few longueurs towards the end, it's one of the best books I've read this year.
