Gina and Laurence have been the best of friends since childhood - but they've never been in love. For that, they chose others: Fergus, who gave Gina a lovely daughter as well as a life of elegance and wealth; and Hillary, who helped Laurence build a cozy, successful hotel - and who counts Gina as a dear friend as well. But when one of these marriages ends, the result is a shift that sends tremors through three generations and two families - as friends become lovers, lovers become enemies, enemies become allies...and another marriage hangs in the balance.
