Have you ever had something you wanted to say to a friend, but couldn't? Ever wished you could go back in time to say something you didn't? Female friendships are some of the most powerful and beautiful relationships in our lives, but it can sometimes be hard to express our true sentiments to these friends. Whether it be pride, fear, feelings, or circumstance that stand in the way, each of us likely has something we wish we could say to someone, but haven't. In "P.S., " Megan McMorris collects these sentiments, as an anthology of unsent letters written by a range of women.
