Nora hates two things: New Year's Eve parties (too loud, too late) and her friend group frenemy, Finn (too tall, too argumentative). Then one New Year's Eve, their friends enforce the "everyone has to kiss someone at midnight" rule and Nora and Finn begrudgingly lock lips. And something about that kiss makes Nora rethink that Finn's mouth might be good for something other than pestering her. Every New Year's Eve over the next five years, Nora and Finn share a kiss. It starts out as an experiment, a test to see if those fireworks she felt the first time were real, but slowly turns into more: a need, a New Year's Eve tradition. But when Finn wants more than New Year's Eve or nothing at all, Nora must decide if she's willing to open herself up to a relationship she never saw coming, if changing everything she thought about New Year's Eve and Finn is worth true love.
