Since childhood, identical twins Leona and Fiona Dunbar have been getting in - and out - of trouble by pretending to be each other. Yet underneath, they couldn''t be more different. Outspoken Leona lives to break rules, have a good time, and scandalize their respectable hometown of Lexington. Fiona is a seemingly-demure churchgoing girl who is the apple of her domineering, widowed mother Mavis''s eye. But together, the twins have fooled teachers, boyfriends, bosses, racist police - and most importantly, strait-laced Mavis. Even when Leona does jail time for Fiona, their unbreakable bond keeps them fiercely loyal... So when Fiona feels stifled in her passionless marriage, and Leona is heartbroken over losing her one true love, it''s perfect timing to change places once again... Leona is shocked to discover she enjoys the security of being a wife and homebody. And the unexpected spark between her and Fiona''s husband is giving her all kinds of deliciously sexy ideas. Meanwhile, Fiona enjoys being free, single, and reveling in the independence she''s never had. And the more she indulges her secret, long-repressed wild child, the more Leona''s ex-lover becomes one temptation she''s having trouble resisting... As the sisters'' masquerade ignites desires and appetites they never expected, it also puts their most damning secrets on the line. Once the fallout rocks their small town, can Fiona and Leona''s deep sisterhood shield them from total disaster and help them reconcile their mistakes? Or will the trust between them become a weapon that shatters their lives for good?
