Marina returned to the city with a portfolio and a small ache that had nothing to do with the angles of the boathouse. She made a project, one that paired the restored images with the cellar’s documents, laid out in quiet contrast: light and careful wood across from a packet of letters smelling faintly of salt. The gallery that took her project was a modest place run by people who liked things unvarnished. The exhibit title was simple and unornamented: Private Island 2013.
