Sara Rauch is in a long-term, committed relationship with another woman when she begins a low-residency MFA in fiction. Though it goes against the promises she?s made, she finds herself pulled into an intense affair with a married man, a well-known writer in the program. More than an essay about bisexual infidelity and the resulting heartbreaks, XO unfolds Rauch?s story like a map of psychic terrain, allowing the author to explore her longstanding obsessions with romantic love, personal faith and belief systems, and the stories we tell ourselves to get through our ever-changing lives.
