Nina LaCour meets Jenny Han in this beautiful and charming story of six moments that lead to two girls, one kiss, and eventually, three little words that were maybe always true.

After years of bickering, Penny and Tate have called a truce: they’ll play nice. They have to. Their mothers (life-long best friends) need them to be perfect, drama-free daughters when Penny’s mother becomes a living liver donor to Tate’s mom. Forced to live together as their moms recover, the girls’ 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 teenaged 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 their kisses—can’t be almosts forever.

Told through the 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.
