I have started How It All Began by Penelope Lively. First book I've read by this author - book club selection, of course. Here's the blurb:
When . . . Charlotte is mugged and breaks her hip, her daughter Rose cannot accompany her employer Lord Peters to Manchester, which means his niece Marion has to go instead, which means she sends a text to her lover which is intercepted by his wife, which is . . . just the beginning in the ensuing chain of life-altering events.
In this engaging, utterly absorbing and brilliantly told novel, Penelope Lively shows us how one random event can cause marriages to fracture and heal themselves, opportunities to appear and disappear, lovers who might never have met to find each other and entire lives to become irrevocably changed.
