According to Dr. Maggie Maguire, happiness is serious science, as serious as Maggie takes herself. But science can't always account for life's anomalies--for instance, why her fiancé dumped her for a silk-scarf acrobat and how the breakup sent Maggie spiraling into an extended ice cream-fueled chick flick binge.

Concerned that she might never pull herself out of this nosedive, Maggie's friends book her as a speaker on a "New Year, New You" cruise in the Gulf of Mexico. Maggie wonders if she's qualified to teach others about happiness when she can't muster up any for herself. But when a handsome stranger on board insists that smart women can't ever be happy, Maggie sets out to prove him wrong. Along the way she may discover that happiness has far less to do with the head than with the heart.

Filled with memorable characters, snappy dialogue, and touching romance, Kristin Billerbeck's The Theory of Happily Ever After shows that the search for happiness may be futile--because sometimes happiness is already out there searching for you.

"Billerbeck has the most delightful voice I've ever read. I adore her stories, and she returns with an enchanting new novel, The Theory of Happily Ever After. I laughed, cried, and rejoiced with her wonderful characters and was sad when the story ended. Highly recommended!"--Colleen Coble, USA Today bestselling author
