"Their friendship went so far back, it bordered on the Biblical: in the beginning, there was Nina and Avery and Mel."

So says high school senior Nina Bermudez, describing herself and her two best friends, aptly nicknamed "the Bermudez Triangle" by a jealous wannabe back on Nina's eleventh birthday. But the threesome faces their first separation when Nina goes away the summer before their senior year.

And in ten short weeks, everything changes.

Nina returns home bursting with stories about Steve, the quirky yet adorable eco-warrior she fell for hard while away, but then when she asks her best friends about their summer romances, an awkward silence follows.

Nina soon learns the shocking truth when she sees Mel and Avery . . . kissing. And she has never felt so excluded from her own friends before.

As Nina works to maintain her tumultous long-distance romance -- and as Mel and Avery navigate their own unexpected relationship, through friendship to enemies to back again -- the Bermudez Triangle finds themselves stumbling toward adulthood, falling in and out of love, enlarging their circle of friends, and rethinking their values, in this warm and humorous tale of friendship . . . and more.
