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 the 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.
