Emily Dickinson and Sue Gilbert grew up spending their summers together in Martha's Vineyard-a small island right off the coast of Cape Cod. Both the Dickinson's and the Gilbert's had summer cottages on the island and they had been summer neighbors since they were young. It had been a few years since Emily had spent her summer there due to college and other life happenings taking up her time previously. They hadn't really kept in touch and this would be the first summer in a while that they would both be there at the same time. As the summer goes on, there's a burning tension between the girls and both of them are feeling it.
