Heartquake

Janis Duke has always been the shadow in her own family-ignored by her mother, dismissed by her twin, invisible to everyone but him. The man she's loved in secret for years. The man who just married her younger sister. Something inside Janis cracks. The quiet, obedient sister is gone. In her place is a woman driven by obsession-watching, waiting, planning. Every look, every touch between them feeds the hunger she can't control.
But obsession is a dangerous game. And when the walls start closing in, Janis must decide how far she'll go to have the life she's always been denied. Walking away would be the sane choice. Making sure he never belongs to anyone else might be her only one. Dark, chilling, and impossible to forget, Heartquake will leave you wondering how well you really know the ones you love-and what they might do to keep you.
