Our host for this month is Rosemary O'Hara.

Our book is "The Last Flight: A Novel," by Julie Clark.

Claire Cook has a perfect life. Married to the scion of a political dynasty, her home is elegant, her days flawlessly choreographed, and her future auspicious. But behind closed doors, nothing is quite as it seems. That perfect husband has a temper and he's not above using his staff to track her every move. What he doesn't know is that Claire has worked for months on a plan to vanish. A plan that takes her to the airport, poised to run from it all. But a chance meeting in the airport bar brings her together with a woman whose circumstances seem equally dire. Together they make a last-minute decision.

The two women switch tickets, with Claire taking Eva's flight to Oakland, and Eva traveling to Puerto Rico as Claire. They believe the swap will give each of them the head start they need to begin again somewhere far away. But when the flight to Puerto Rico crashes, Claire realizes it's no longer a head start but a new life. Cut off, out of options, with the news of her death about to explode in the media, Claire will assume Eva's identity, and along with it, the secrets Eva fought so hard to keep hidden.
