The Other Woman — Jane Green

In Jane Green's delicious novel, the Other Woman is the mother-in-law. Ellie thinks she's found the perfect man in Dan, and she loves being accepted as part of his close-knit family. Until she begins to realize that Dan's mom, Linda, is a little too involved. Dan and Linda talk on the phone every day. Twice a day. And then, as Dan and Ellie's intimate civil wedding ceremony gets transformed into a black-tie affair, Ellie begins to wonder if it's possible to marry the man without marrying his mother.

As troubles mount, Ellie turns to her friends--glamorous Lisa and wonderfully frazzled Trish--and tries to rediscover the independence she once had, and the man she still loves. But it seems that having a child and saving a marriage means growing up in ways she'd never imagined. . . .
