Kirsten Nilson was in a sort of rut. She was living in a teeny tiny apartment, working a boring job (with people she hates) and also alone (apart from her pet cat, Scooters). Her monotonous life gets absolutely flipped (maybe even twisted) when she attempts a little juvenile (but at the time totally worth it) revenge, and ends up gaining a new tenant in her home...and her body...and her mind...And as she attempts to exercise herself of this problem, she gets even more tangled in it...
