Awakening Sexual Identities

Fourteen-year-old Krista McKinley finds herself a stranger in a strange land when she, her mom, and her two older stepbrothers move from Ohio, where she attended a Catholic private school, to California, where she gets enrolled at Crestmount High, a public school. She faces culture shock and experiences confusion about dating, being around boys as schoolmates for the first time, and questions her own sexual preferences in the debut coming-of-age novel Torn, by Amber Lehman. It'll pull at your heartstrings, and make you feel for Krista's situation and her inner turmoil, wanting to fit in, but also desiring to be true to herself. Is it just a "phase" she's going through, as her brothers Josh and Marc suggest; or, are her feelings for her best friend, Carrie, something more?
The situation Krista is in is a bit strange on a few levels. Her mom and dad are divorced, and her mother is a missionary who is in Nicaragua for a year, leaving her in the charge of her two stepbrothers. Josh and Marc do the best job they can serving as both her brothers and parents en-absentia, but they are no substitute for the real thing. Also, I couldn't help but wonder about California's laws regarding this sort of arrangement, and if her mother's not being there might be considered to be a case of child abandonment or neglect. Still, looking beyond that issue, I thought the novel was a sensitive treatment of an issue that affects many youths - the questioning of who they are, and how they should act and behave socially and sexually.
Besides her girlfriend Carrie, one of her best friends is Brandon. Brandon is a surfer, and he's very wealthy, athletic, popular, good-looking, the kind of guy other guys admire and girls fall in love with - but, he's also gay. Most of the other guys mentioned in Torn have either had sex with Brandon or also question their sexual identities. He's had sex with teen girls his own age, but he knows he's gay, and is comfortable with this realization. He's witty, and somewhat catty, and has a great sense of fashion. Carrie introduces him to Krista early on in the novel, and the three become close pals. Brandon suspects that Krista wants to be more than friends with Carrie, and vice-versa, and he encourages Krista to pursue her feelings.
Brandon is a great friend for Krista in many ways, and an interesting and colorful character. He even becomes Krista's date to the prom. Still, I wondered if Krista maybe wouldn't have ended up questioning her sexual preferences if she had first become friends with heterosexual guys at her new school instead of Brandon and his male friends. It's one thing for Brandon to know who he is and be cool with it, but not everyone is as self-assured or has had as much sexual experiences as he claims to have had. Krista has gone to school only with other girls previously, and has not had any sexual feelings for them, and she's only fourteen, after all. Being around other young people who have had sex likely makes her feel she has to play catch-up with them.
