Bill's law firm houses the Holden family in Paradise Mansions - a luxury apartment block full of 'second wives': beautiful young women like JinJin Li, ex-school teacher, crossword addict, dedicated roller skater and the Holden's neighbour.
After Becca witnesses a near-tragedy, she returns temporarily to London with Holly - and Bill and JinJin are thrown together.
Bill wants to be a better man than the millionaire who keeps JinJin Li as a second wife. Better than any man who cheats. Becca is his best friend. But in the end can he give JinJin anything different - can he give her the love she deserves? And can he love his wife too?
My Favourite Wife is a book about the men and women of our time - their struggles, their joys and their secret longings. Above all it is a book about where sex, romance and obsession ends, and where true love begins.
