The more feisty and highly strung of the Mulroney twins, Kirsten is bright, scholastic and determined. But, right now, she's turning all that energy into anger towards her father, but mostly her father's new girlfriend, Bec Quilter.
Having to move away from your school and your friends when you're in Year 10 is a nightmare for anyone – knowing that your mother has deserted you and you're stuck having to deal with a manipulative, brainwashing cow like Bec is the worst. For this reason, Kirsten thinks she's justified in her right to seek revenge against Bec but, on a deep level, she really feels abandoned and rejected by her parents.
Kirsten has actually known for some time that her parents weren't happy, but is blaming Bec for breaking up her family and will do anything to make her pay.
