Pulp by Robin Talley.
In 1955, eighteen-year-old Janet Jones keeps the love she shares with her best friend a secret. In the age of McCarthyism to be gay is a sin. But when Janet discovers a series of books about women falling in love with other women, it awakens her need to write. As she juggles a romance she must keep hidden and a newfound ambition to publish her own story, she risks exposing herself, and Marie, to a danger all too real.
Sixty-two years later, Abby Zimet can’t stop thinking about her senior project: classic 1950s lesbian pulp fiction. She feels especially connected to one author, Marian Love, and becomes determined to track her down and discover her true identity. But is Abby prepared for what she will find?
