The summer before senior year. Lazy afternoons in Jill's pool, an all-out TP-ing war, wild parties at Landon's. Friendship, jealousy, revenge, love. Hillary is more into Dirk than ever, and even though this summer is bittersweet for Hilton and Lorylyn because of Landon's and Brady's imminent departures, both girls agree their relationships are the best they've ever been. Not everything is perfect though...Todd's parents' divorce is turning nastier by the day, and Jill desperately clings to increasingly infrequent moments with him as his bond with Melanie grows more intense. As hot sunny days roll into warm breezy nights, the date that's been set for months draws closer and closer...the night of the goodbye party. The circle of friends has been coming to Landon's for three years to dance, drink, skinny-dip, and play spin the bottle, and on August 18, it will happen for the last time. And it's going to be the biggest and craziest and best party of all...Or so they think. For at this party, the shattering secret that has been kept hidden for three years will be revealed, in an unforeseeable moment that will rock the lives of every person who's been a regular at Landon's over the years. It will destroy their beliefs, perceptions, and illusions, and it will break the circle of friends forever. And as the ex-seniors go off to college, Jill, Hilton, Lorylyn, Hillary, Todd, Dirk, and Bennett are left to pick up the pieces and try to salvage their senior year...
