It’s 2003, and artist Dawn Levit is stuck. A bookbinder who works at the Metropolitan Museum of Art, she spends all day repairing old books but hasn’t created anything of her own in years-and with nothing ready to show at her major gallery debut in six weeks, time is of the essence. What’s more, although she doesn’t have a word for it yet, Dawn is genderqueer and she’s struggling to feel safe expressing herself.

One day at work, Dawn discovers something hidden under the endpapers of an old book: the torn-off corner of a 1950s lesbian pulp novel, with an illustration of a woman looking into a mirror and seeing a man’s face. Even more intriguing is the queer love letter written on the back. Dawn becomes obsessed with tracking down the author of the letter, convinced the mysterious writer can help her find a place in the world and also solve the trickiest puzzle of all: how she truly wants to live her life.
