What happens in Puerto Rico doesn't always stay there. . .

Mariana Ruiz thought she left her summer fling in Puerto Rico, that is until she finds Alex sitting across from her at the breakfast table. Living two doors down from her visiting old flame isn't easy, especially given the unresolved sparks still lingering for her locker buddy Bobby--and they don't exactly go unnoticed.

Her best friends are little help as Madison deals with her IM-only "boyfriend" and Emily sinks into secret mode after her parents' recent breakup. The only relationship that seems to be working is her estranged aunt Teresa who's tying the knot on New Years with Mariana and her cousin Lilly as bridesmaids. But the last wedding detail left unplanned is who will Mariana kiss at midnight?

Strained friendships, stolen kisses, and secret loves create plenty of surprises to unfold before the New Year's bells start ringing. . .
