For sixteen-year-olds Anna Reiley and Frankie Perino, their twenty day-long, minimally supervised California vacation will be the 'Absolute Best Summer Ever' and according to Frankie, if they meet one boy every day, there's a pretty good chance that Anna will get her first real boyfriend. Anna lightheartedly agrees to the game, but there's something she hasn't told Frankie - she's already had that kind of romance, and it was with Frankie's older brother, Matt, just before his tragic death one year ago.
