After years of bickering, Penny and Tate have called a truce: They'll play nice. They have to. Their mothers (lifelong best friends) need them to be perfect, drama-free daughters when Penny's mother becomes a living liver donor to Tate's mom. With the girls forced to live together as the moms recover, their truce is essential in keeping everything -- their jobs, the house, the finances, the moms' healing -- running smoothly. They've got to let this thing between them go. There's one little hitch: Penny and Tate keep almost kissing. It's just this confusing thing that keeps happening. You know, from time to time. For basically their entire teenage existence. They've never talked about it. They've always ignored it in the aftermath. But now they're living across the hall from each other. And some things -- like kisses -- can't be almost forever. Told through two girls' present and six moments from their past, this dynamic love story shows that sometimes the person you need the most has been there for you all along.
