What can we do when it's too late to fix the mistakes of the past? Letters, written and composed by Daniel Schwartzman, is a musical about Frida, a middle-aged writer of children's books long estranged from her parents. The reasons come into focus as the action progresses, moving back and forth through time. With her parents recently deceased and no longer a threat to her stability, Frida decides to finally read the letters they had sent her over the years, all unanswered. She is joined by visions of her mother and father as she reads the letters, often leading into highly charged scenes. As Frida grows from age 5 to 16, we watch a creeping toxicity take over their household, eventually destroying the family. In the final third of the musical, we discover where this began. Frida's beloved younger brother, Mikey, drowned in the sea at age six while the parents had one of their nasty arguments nearby. Frida was present at the scene and it left her changed forever.
