Dissing You Already — Kate Kingsley

Addictive, risqué, glamourous fiction series for sophisticated teens.
Alice and Tally, the most gorgeous, glamorous girls at St Cecilia's, are best friends. But since Alice shared a fabulously romantic tryst with Tally's ex during a New Year's skiing trip, it seems only a matter of time before things get ugly.
But Tally seems too distracted to notice Alice's guilty behaviour. Where did she disappear to over the Christmas break? Where has she got hold of the cash she's flaunting around? And where has she got the beautiful new necklace with its mysterious coat of arms. Alice hopes it doesn't have anything to do with the scary sounding Russian connections Tally's boasted of.
The new term will bring gossip, glamour and scandal than ever before...
