Sisterland by Curtin Sittenfeld

I just love this author..... An American Wife was so engrossing.... and so is this book! It is the tale of two identical twins, Kate and Violet (Vi) who have "psychic abilities," although Kate is not really into it anymore. She has worked hard to mask her "sixth sense" by transforming herself into an ordinary wife to loving, even-keeled husband Jeremy and mother of two adorable kids, but she has enormous insecurities. Kate and Jeremy's neighbors are Courtney (who is also Jeremy's colleague) and her stay-at-home husband Hank, who is Kate's best friend. Vi is an exuberant, self-centered self-promoter who gives psychic readings for a living. When an earthquake rattles St. Louis in September 2009, Vi's prediction that a much bigger one is on the way gains national traction, setting off a media circus and geographic panic. As well, Kate's reluctant, growing involvement in Vi's life leads to a shocking, seismic disruption on her home front.
