Yolk

Jayne Baek is a fashion design student in New York, scraping through classes and hiding a long-running eating disorder from nearly everyone. Her older sister June, three years ahead of her and a success in hedge funds, has barely spoken to her since the two of them moved from Seoul to San Antonio to New York together as girls. Then June is diagnosed with cancer, and without insurance of her own she quietly uses Jayne's identity and school coverage to get treated.

When Jayne finds out, she demands a place in June's Manhattan apartment as the price of her silence, and the two sisters end up sharing a home neither expected to. Jayne cooks, cleans and watches June get sicker, while her own relationship with food and her body gets harder to ignore.

Yolk is a young adult novel narrated by Jayne. It is a deliberately paced, character-driven story about sibling resentment, Korean American identity, family, health and the American healthcare system, and it follows what two very different sisters owe each other.
