Christina Smith

Christina Smith is Leo Smith's older sister. Leo thinks she is a whore and a party animal. She is starting her junior year of high school in Book 1, making her a year older than Leo.

Personality
Christina is charming, friendly, outgoing, and vivacious. She is also very promiscuous: on the first day of school, she instantly starts flirting with two boys and, within seconds, is making out with them.She later brags that on her first day she made out with six different guys, "two at the same time!" Leo thinks lowly of her because of this.

Although she seems frivolous, she does show signs of being a good sister. She is concerned about Leo when he comes home bruised from his fight with Ace, and although she promises to lie to their parents for him, she does mention that if he has any problems he should talk to her.

Appearance
Christina is blonde and attractive. She is tall with a slender waist and very big breasts. She has brown eyes and long, wavy dirty blonde hair. She is usually seen wearing a tiny pink tank top that exposes much of her cleavage and midsection as well as short shorts and long white boots. She is usually heavily made up.

Book 1: The New Kid
Christina is the first character to be introduced in the series, excluding Leo. Leo mentions that she is a year older than him (making her a high school junior at the start of the series) and that she has no trouble making friends, although it's pretty clear by the pictures that this is just a euphemism. Christina meets two guys her age and promptly starts making out with them. Later on, she tells Leo that on her first day of school she was able to make out with six different guys, "two at the same time!"

After Leo's fight with Ace, Christina shows that she is concerned about Leo. Leo decides he'll retire to bed early, mostly so his parents won't see his injuries, and Christina promises to lie for him, although she makes sure to let him know she's worried about him and wants him to talk to her if he feels he needs to. Later on in the book, Christina is mentioned to go out a lot, mostly to parties or out with guys, making Leo jealous that she makes friends so easily.

Trivia

 * Like most characters, her personality is derived from her name. Christina means Christian-like, which is very ironic as she is essentially the total opposite of a good Christian girl. Smith is the most common name in the USA; unlike Leo, where this lack of  originality matches his personality, Christina's surname instead implies that she's "common goods," or that every boy has essentially has a shot at her because she's a whore.
