After they cause a terrible accident at their old high school, twin witches Mardi and Molly Overbrook are sent to live with their "Aunt" Ingrid Beauchamp in North Hampton, on Long Island's mist-shrouded East End. Because the twins cannot control their powers, their father begs Ingrid to tame them over the summer, before the White Council exiles the girls to Limbo.
Trouble continues to bubble and boil when the girls meet the younger Gardiner boys, who are just as handsome and sexy as their older kin. But all is not as it seems. As Ingrid helps the girls learn to control their magical impulses, Mardi and Molly have just this summer to figure out how to grow up, how to love, and how to be a family.
