When longtime rivals Rowan Roth and Neil McNair confessed their feelings on the last day of senior year, they knew they'd only have a couple months together before they left for college. Now summer is over, and they're determined to make their relationship work as they begin school in different states.

In Boston, Rowan is eager to be among other aspiring novelists, learning from a creative writing professor she adores. She's just not sure why she suddenly can't seem to find her voice.

In New York, Neil embraces the chaos of the city, clicking with a new friend group more easily than he anticipated. But when his past refuses to leave him alone, he doesn't know how to handle his rapidly changing mental health--or how to talk about it with the girl he loves.

Over a year of late-night phone calls, weekend visits, and East Coast adventures, Rowan and Neil fall for each other again and again as they grapple with the uncertainty of their new lives. They've spent so many years at odds with each other--now that they're finally on the same team, what does the future hold for them?
