Iodine

From her earliest years, Trace turned away from her abusive mother toward her loving father. Within the twisty logic of abuse, her desperate love for him took on a romantic cast that persists to this day, though she's had no contact with her family since she ran away from home years ago. Alone but for her beloved dog, she's eked out an impoverished but functional existence, living in an abandoned house, putting herself through college, and astonishing her teachers with her genius and erudition. What they don't know is that she leads a double life: thanks to forged documents, at school she is Ianthe Covington, a young woman with no past. Trace's singular life is upended when she and her literature professor fall in love. She tells him nothing about her life, and as it becomes apparent that he has his own dark secrets, she's forced to face herself and her past. After recovering a horrific, long-suppressed memory, Trace finally copes with the fallout from her brutal, bizarre childhood.--From publisher description.
