At thirty-two, June Hale walks out of a life she has built on schedule. She quits the job. Sells the apartment. Ends the relationship she was supposed to keep. And she goes, with one suitcase and one rule, to a borrowed villa above the sea on the Amalfi coast. The rule is simple. For the next ninety days, she says yes. To swimming in the cold sea at midnight. To strangers. To the second-cheapest white wine. To picking lemons in a garden behind a house that isn't hers. To Nico - a half-Italian, half-American musician with a small old scar at the line of his jaw, a girlfriend back in New York, and a quality of attention that doesn't divide. What was supposed to be a single reckless night becomes a summer that rewrites who she thought she was. Told in twelve chapters, one for each week of summer, in the present tense - because she did not, at the time, know how it would end. For readers who finished Daisy Jones & The Six in a weekend and stayed up late after Call Me By Your Name. What if the love that changes you isn't the one you're meant to keep?
