The Comfort of Lies - Randy Susan Meyers

In this "sharp and biting, and sometimes wickedly funny" (The Boston Globe) bestselling novel, three very different families are threatened in the wake of an extramarital affair.
Five years ago . . .
Tia fell into obsessive love with a man she could never have. When she became pregnant, Nathan disappeared, and she gave up their baby for adoption.
Caroline reluctantly adopted a baby to please her husband. Now she's ques-tioning whether she's cut out for the role of wife and mother.
Juliette considered her life ideal: solid marriage, two beautiful sons, and a thriving business. Then she discovered Nathan's affair. He promised he'd never stray again, and she trusted him.
Now . . .
When Juliette intercepts a letter to her husband that contains pictures of a child who deeply resembles him, her world crumbles once more. How could Nathan deny his daughter? What other secrets is he hiding? Desperate for the truth, Juliette goes in search of the little girl, and before long the three women are on a collision course with consequences that none of them could have predicted.
