Seven Year Switch — Claire Cook

They say that every seven years you become a completely new person.

Just when she's finally figured out how to manage on her own, Jill Murray's ex-husband, Seth, is back -- crashing into the man-free existence Jill and her ten-year-old daughter, Anastasia, have built so carefully. Enter free-spirited entrepreneur Billy, who hires Jill as a consultant for an upcoming business trip. Suddenly, her no-boys-allowed life is anything but. It takes a Costa Rican getaway to help her make a choice -- not so much between the two men in her life, but between the woman she is and the woman she wants to be.
