"On Chesil Beach" by Ian McEwan
A quite short book (166 pages) but McEwan does his usual magic. A beautifully touching and ultimately rather sad story about a couple from different backgrounds who meet, fall in love, marry, and part. Their meeting and their parting really just turned on a few seconds that could have been different. I'm always fascinated by how much of life does turn on a few seconds that have life changing results.
