"Hannah believes she has the talent to be a great writer. You know, once she actually writes something. In the meantime, she's trying to hold down a paying job now that her parents have cut her off financially and she's without a safety net for the first time. At 24, Hannah is still dependent on her mom and dad. Further complicating things is her unrequited passion for her pseudo-boyfriend Adam (boyfriend is the polite term for it) but she's not sure she's ready for something grown-up anyway."
Hannah was born and raised in East Lansing, Michigan. Her parents are Tad and Loreen Horvath, both university professors (presumably at Michigan State University, which is in East Lansing).
