From New York Times bestselling author Mary H.K. Choi comes a funny and emotional story about two estranged sisters and how far they'll go to save one of their lives - even if it means swapping identities.Jayne and June Baek are nothing alike. June's three years older, a classic first-born, know-it-all narc with a problematic finance job and an equally soulless apartment (according to Jayne). Jayne is an emotionally stunted, self-obsessed basket case who lives in squalor, has egregious taste in men, and needs to get to class and stop wasting Mom and Dad's money (if you ask June). Once thick as thieves, these sisters who moved from Seoul to San Antonio to New York together now don't want anything to do with each other.That is, until June gets cancer. And Jayne becomes the only one who can help her.Flung together by circumstance, housing woes, and family secrets, will the sisters learn more about each other than they're willing to confront? And what if while helping June, Jayne has to confront the fact that maybe she's sick, too?
