Incarceron by Catherine Fisher
Incarceron -- a futuristic prison, sealed from view, where the descendants of the original prisoners live in a dark world torn by rivalry and savagery. It is a terrifying mix of high technology -- a living building which pervades the novel as an ever-watchful, ever-vengeful character, and a typical medieval torture chamber -- chains, great halls, dungeons. A young prisoner, Finn, has haunting visions of an earlier life, and cannot believe he was born here and has always been here. In the outer world, Claudia, daughter of the Warden of Incarceron, is trapped in her own form of prison -- a futuristic world constructed beautifully to look like a past era, an imminent marriage she dreads. She knows nothing of Incarceron, except that it exists. But there comes a moment when Finn, inside Incarceron, and Claudia, outside, simultaneously find a device -- a crystal key, through which they can talk to each other. And so the plan for Finn's escape is born ...
Boys That Bite (Blood Coven #1) by Mari Mancusi
This is not your typical boybites-girl love story.
Technically Sunshine can't get killed-because she's immortal. Well, not quite yet. Due to the worst case of mistaken identity with her dark-side-loving twin sister at a Goth club called Club Fang, Magnus, a vampire hottie, went for Sunshine's innocent neck. Now if she doesn't reverse it in time, Magnus will be her blood mate forever and she's doomed to be a blood-gulping, pasty, daylight-hating vampire. That would seriously bite.
And now, after the unfortunate slaying of the vampire leader, Sunshine, her sister Rayne, and Magnus must find the one thing that can solve her problem: the Holy Grail. They wish it were a joke but it's not. It's absolutely necessary that Sunshine gets out of this in time, because somehow she scored the hottest prom date in her school, the mouth-watering Jake Wilder. So she just can't be a vampire for the prom-let alone the rest of eternity.

Some Girls Are by Courtney Summers
Climbing to the top of the social ladder is hard--falling from it is even harder. Regina Afton used to be a member of the Fearsome Fivesome, an all-girl clique both feared and revered by the students at Hallowell High... until vicious rumors about her and her best friend's boyfriend start going around.
Now Regina's been "frozen out" and her ex-best friends are out for revenge. If Regina was guilty, it would be one thing, but the rumors are far from the terrifying truth and the bullying is getting more intense by the day. She takes solace in the company of Michael Hayden, a misfit with a tragic past who she herself used to bully. Friendship doesn't come easily for these onetime enemies, and as Regina works hard to make amends for her past, she realizes Michael could be more than just a friend... if threats from the Fearsome Foursome don't break them both first.
Tensions grow and the abuse worsens as the final days of senior year march toward an explosive conclusion in this dark new tale from the author of Cracked Up To Be.
