Isabel thought her life was on track - she was doing well in college, moving quickly toward her future, and deciding who she wanted to be. Best of all, she'd reunited with Tom, the swim coach she had a secret affair with in high school. But it doesn't take long for her history - and his - to start catching up with them. When Isabel goes back to her college life, after spending a blissful summer reuniting with Tom, things take a dangerous turn. Isabel gets swept up in a relationship with a dark, mysterious professor, with whom she begins a covert love affair that could ruin everything she has rebuilt with Tom. Worse, she starts to hear rumors from friends back home - rumors about a teacher having affairs with students. And Tom seems to be at the center of the controversy. Will Isabel's instincts about what Tom's been up to during their time apart drive her farther away, or will she forgo her new romance to run to Tom's defense?
