Finding Grace by Loretta Rothschild

Honor seems to have everything: she adores her bright and beautiful daughter, Chloe, and her charming, handsome husband, Tom, even if he works 100 hours a week. Yet Honor's longing for another baby threatens to eclipse all of it - until a shocking event changes their lives forever. Years later, Tom makes a decision that ripples through their families' lives in ways he could never have foreseen. As the consequences of that fateful choice unfold, two women's paths become irrevocably intertwined. But when old love clashes with new, who will be left standing? And what happens when your secrets come back to haunt you?
