Just when Romero thought he'd conquered his anger issues. Now that Izzy has earned her credentials to teach at a college level, Romero is doing his best to be supportive. Even after she informs him she won't be teaching. She'll be assisting a professor-a recently divorced professor whom she'll work with side by side. Isabel loves being home with her kids, but she's ready to get back to her career-back to a world where she can enjoy some in-depth political conversations with someone who really gets it. The brilliant Political Science professor she's assigned to assist seems to be the perfect fit. But when those conversations get a little personal, Isabel isn't sure if she's just being silly or if the professor is sending insidiously veiled messages. Romero's knack for picking up on her unease only complicates things, especially because Isabel also has a big Christmas surprise for him.

With suspicions awakened, Romero's interpretation of Isabel's sneakiness stirs that dormant rage he hasn't had to deal with in years, and emotions become furiously Tangled.
