Penelope and Chase make a lovely couple. She's a bubbly Southern California girl with killer work ethic. Chase is smart and charming and has political aspirations. They're planning a spectacular California wedding, wrapped in peonies and thousands of little white lights, soaked in custom cocktails and romantic hashtags. Everyone's excited about Penny and Chase's wedding--------except their mothers. The Mother of the Bride, suave Greek-born Alexa Diamandis, doesn't understand why any woman would get married. Ever! Raised in Athens and now perfectly situated in sun-splashed Montecito, California, she raised Penny as single mother by choice, supported by Lord Simon Fox, her old college friend who just happens to be an English aristocrat, and a wealthy circle of lady friends who call themselves the Merry Widows. The Mother of the Groom, Abigail Blakeman, is a garden club stalwart firmly planted in coastal Connecticut. She thinks the whole enterprise would be so much easier if the wedding was at their golf club. Especially because the Blakeman's fortunes have taken a turn for the worse--not that you would ever know it by looking at Abigail. Keeping up appearances is exhausting, but it is everything. But when a sudden twist of fate calls them into action, these two very different women are forced to take over the wedding planning. Despite their differences, Alexa and Abigail charge in to save the day. How far will two moms go to make their children's dream wedding a reality?
