Addiction by Ivy Smoak

Temptation has quickly turned into addiction. Penny fell hard for her mysterious professor, but secrets have torn them apart. After all, scandalous affairs are meant to go down in flames.

Now that he's not speaking to her, she feels numb. And what hurts the most is that he appears to be completely fine. As she struggles to accept that their relationship is really over, her best friend's crude advice is in the back of her mind- the best way to get over someone is to get under someone else.

Will she be able to move on, or is her addiction to her alluring professor only just beginning?
