While her daughters Abby and Penny are visiting their grandmother on Maggie's beloved East Coast, Maggie discovers something in Abby's diary that gives her cause to worry -- and reason to hop on a plane to join them. While in Nova Scotia she runs into an old boyfriend who raises emotions and questions that Maggie hadn't thought about since she left more than 16 years ago. Abby too learns things about her mother that she never knew before. Both are pulled back to the past and their relationship is threatened in more ways than one.
