American Wife by Curtis Sittenfeld. 
It was fabulous and I highly recommend it. Sittenfeld's third novel following the NYT bestseller Prep, this novel is a fictional portrayal of Laura Bush's life. Of course nowhere in the book does it mention the name of Mrs. Bush or anyone related to her which allows Sittenfeld to delve into the depths of what she imagines Laura's life to have been like without worrying about having to deal with the White House.
“A well-researched book that imagines what lies behind that placid façade of the first lady…Ms. Sittenfeld was not out to sensationalize but to sympathize."
–Maureen Dowd, The New York Times
“Brilliant…[A] triumph…Curtis Sittenfeld has provided a plausible secret history of an American embarrassment – and a grand entertainment.”
–Joe Klein, Time Magazine
“A smart and sophisticated portrait of a high-profile political wife…Sittenfeld has an astonishing gift for creating characters that take up residence in readers’ heads.”
–Connie Schultz,Washington Post Book World
“Sittenfeld boldly imagines the inner life of a first lady…an intimate and daring story…American Wife is a vicarious experience, an up-close portrait of the interior life of a very complicated woman…cinematic.”
–USA Today
“The novel, Sittenfeld’s most fully realized yet, artfully evokes the painful reverberations of the past.”
–New Yorker
“Compelling...enormously sympathetic...Sittenfeld’s remarkable gifts as a storyteller draw you back into the fictional world of Alice Blackwell. She writes in the sharp, realistic tradition of Philip Roth and Richard Ford–clear, unpretentious prose; metaphors so spot-on you barely notice them. Sittenfeld may have lifted the set pieces from a real woman’s life, but in the process she has created a wise and insightful character who is entirely her own.”
–Time Out New York
