Holly Renee Larson (born January 17, 2010) is a quarter-blood.
Nick loves her and her siblings, despite the fact that they aren't biologically his children.
Holly is a Caucasian female. She has light skin, blonde hair and light brown eyes. Though she has her father's blonde hair, she has her mother's everything else.
Holly is a very sweet little girl. She's playful, but can be a little shy at times. As a teen, Holly dresses punk-ish but isn't really much of a punk (a bit like Demi Lovato). She is brave and can be a little grumpy sometimes, a lot like her maternal grandmother. She's lazy, a bit sloppy, and clumsy. One of her quirks is always pulling her hair into a ponytail; it keeps it out of her eyes and lets her think. She has ADD, dyslexia, and minor OCD. She's sometimes flirty, like her parents.
