As a child, Meg Medina’s days were awash with stories oceans away from the likes of “Goldilocks and the Three Bears.“ “My grandmother . . . she rolled cigars as a young woman [in Cuba], and she still smoked as an old lady,“ Medina said of her grandmother, who had given up cigars, but not the habit of smoking, by the time she became Medina’s after-school sitter.
