2. Bloodlines by Richelle Mead
3. Thirteen Reasons Why by Jay Asher
I know that some of these weren't published in 2011, but I read them first this year and that's what I'm basing this list off of.
Goodreads description: Jason Vanderholt, Hollywood's hottest actor, falls head over heels for everygirl, Chloe Winters, who hasn't gotten around to watching most of his movies. It's the ideal fairytale... for most people. The last thing Chloe needs is public attention as this brings back dangers from the past that she's worked her whole life to escape.
Goodreads description:When fifteen-year-old Clary Fray heads out to the Pandemonium Club in New York City, she hardly expects to witness a murder - much less a murder committed by three teenagers covered with strange tattoos and brandishing bizarre weapons. Then the body disappears into thin air. It's hard to call the police when the murderers are invisible to everyone else and when there is nothing - not even a smear of blood - to show that a boy has died. Or was he a boy?
Goodreads description: When a college freshman's breakthrough software program catapults her into the limelight, she and her twin brother must navigate a treacherous world of money, power, and envy: Silicon Valley.
