It's All About Us (All About Us, #1)

Tall, blonde Lissa Mansfield is used to being one of the "in" crowd--but being accepted by the popular girls at posh Spencer Academy boarding school in San Francisco is turning out to be harder than she thought. And then there's her New-York-loudmouth roommate, Gillian Chang, who's not just happy to be a Christian herself--she's determined to out Lissa, too! If Lissa can just keep her faith under wraps long enough to hook Callum McCloud, the hottest guy in school, she'll be golden.
But when Callum pressures her to go all the way with him, Lissa has to decide for herself how far is too far. How can she see that line when he's so gorgeous and popular and she's so dazzled? And besides, she's too busy shopping for a Valentino and booking the hottest celeb for the Benefactors Ball. Who knew finding a place at Spencer Academy would be so complicated?
