Well, I read the first in the series because these books are often Billed, and I was curious. The A-List is admittedly shallow, with consumerism overload. Versace, Hermes Kelly, and Burberry brand-name-dropping might be a quick way to communicate wealth, but it's not very good writing. Still, I was reminded of my thought after sampling Gossip Girl as well: that fantasy is broadly defined as another world, and for some this may consist of elves and unicorns, and for others, the lives of the super-rich and unsupervised. Gossip Girl at least has a narrator who is out to make fun of the protagonists and their spoiled ways and bad decisions, while this book relies on the goodness of Anna to redeem it slightly. Very catty; includes language, sex, drinking and drugs (mostly off-screen). 
 Quotes: 
 "In Sam's opinion, Cammie had the depth of the cup size she'd worn before she had her breasts done." 
 "She tended to see her life as a movie anyway, mentally scoring her most dramatic moments, mentally framing her most visual moments, mentally scripting her most important conversations." 
 "'I now pronounce you soul mates,' said the minister." (LOL!) 
 "A girl like Anna was like skim milk -- you felt virtuous drinking it, but eventually you just had to have a milkshake. Cammie knew that she was the milkshake." 
 "I got dumped tonight by a boy who pretended that he thought I was a precious diamond and then threw me away like so much cubic zirconia." (LOL again!) 
 "Nothing gold can stay." -Robert Frost
