After a tumultuous junior year, best friends Lila Moreno, Meryl Morganstern, and Caressa Thibodoux plan to make the most of the summer before senior year. But those plans fall by the wayside when Lila's archenemy, Jennifer Hamilton, finds herself friendless and flailing in a mess of her own making. Meryl steps up to help...and drags Lila and Caressa along with her.

What was supposed to be a carefree few months morphs into a summer of girl power, growing up, and giving in to situations beyond their control. In the end, all four girls are tighter than ever and one step closer to tackling their all-important senior year.
