The Darby-Jones boarding house in Ruby Falls, New York, is home to Mona Jones and her daughter, Oneida, two loners and self-declared outcasts who have formed a perfectly insular family unit. But their small, quiet life is upended when Arthur Rook shows up, devastated by the death of his wife, carrying a pink shoe box containing all his wife's mementos including a postcard from sixteen years ago, addressed to Mona but never sent. Slowly the contents of the box begin to fit together to tell a story - one of a powerful friendship, a lost love, and a life altering secret. The truths it brings to light will teach everyone about love - how deeply it runs, how strong it makes us, and how tightly it brings us together. With emotional accuracy and great energy, This Must Be the Place introduces memorable, charming characters that refuse to be forgotten.
