Hello beautiful by Ann Napolitano

Best friends and sisters, the four Padavano girls are seen as inseparable by everyone in their close-knit Italian-American neighbourhood. From childhood, the four sisters complete each other. When Julia falls in love with William Waters, a history student and college sports star, she's delighted by the way her plans for adulthood are coming to fruition: a husband, a house, a family of her own. But when darkness from William's past begins to block the light of his future, it is Sylvie, not Julia, who becomes his closest confidante - and the ensuing betrayal tears the sisters apart.
