Violinist Anna Sun is burned out from the pressure of unexpected internet fame, and when her longtime boyfriend asks for an open relationship, she impulsively starts seeking one-night stands of her own. She unexpectedly connects with Quan, a tattooed clothing designer, and what begins as a fling grows into something deeper just as a family crisis forces Anna into an exhausting caregiver role. The book blends romance with a candid look at autism, burnout, and family obligation, making it more emotionally heavy than the earlier books in the series.
