Mallory’s fine—really—handling the wedding arrangements for her ex, Keith. But his fiancée, Becca, has at the last minute decided to switch from a Japanese-cherry-blossom theme to a Gone with the Wind theme. She wants to honor her ailing grandmother, who owns an impressive collection of Gone with the Wind memorabilia—and who is fiercely at odds with the groom’s mother over the nuptial plans. But among other complications, Becca gets into a fight with an old childhood rival over a replica Scarlett O’Hara wedding gown. She wins the dress—but soon becomes a murder suspect when the other woman is found dead in Becca’s swimming pool. And it’s up to Mallory to solve the mystery behind this unhappy occasion, before a different kind of civil war breaks out.
