Pretty Little Dirty — Amanda Boyden

LISA SEES THE LIFE OF HER GORGEOUS BEST FRIEND CELESTE DIAMOND AS JUST ABOUT PERFECT: she has a gigantic house, two older sisters to coach her through the hazards of high school, and loving, lively parents.

As Lisa's own home has long been a place devoid of joyful noise, she joins the Diamond household, slipping into their routine of sit-down suppers and soaking in the delicious normalcy of family life. But what begins as the story of two young women living a charmed existence soon swirls into an intoxicating novel of art, music, and self-destructive impulses.
