I don’t know if they are official yet, but I found those three covers while browsing =)
First one is Entice by Carrie Jones, the third book in the Need series.
Zara and Nick are soul mates, meant to be together forever. But that's not quite how things have worked out.
For starters, well, Nick is dead. Supposedly, he's been taken to a mythic place for warriors known as Valhalla, so Zara and her friends might be able to get him back. But it's taking time, and meanwhile a group of evil pixies is devastating Bedford, with more teens going missing every day. An all-out war seems imminent, and the good guys need all the warriors they can find. But how to get to Valhalla?
And even if Zara and her friends discover the way, there's that other small problem: Zara's been pixie kissed. When she finds Nick, will he even want to go with her? Especially since she hasn't just turned. She's Astley's queen.
it’s suppose to release in December 2010 =)
Up next is Heaven’s Spite by Lilith Saintcrow, the fifth book in the Jill Kismet series
When a new hellbreed comes calling, playing nice isn't an option. Jill Kismet has no choice but to seek treacherous allies - Perry, the devil she knows, and Melisande Belisa, the cunning Sorrows temptress whose true loyalties are unknown.
Kismet knows Perry and Belisa are likely playing for the same thing--her soul. It's just too bad, because she expects to beat them at their own game. Except their game is vengeance.
Nobody plays vengeance like Kismet. But if the revenge she seeks damns her, her enemies might get her soul after all...
This one is suppose to release November 2010!
Last one is Awakened UK by PC & Kristen Cast, eighth book in the House of Night series
At the start of Awakened, the pulse-pounding eighth installment of the bestselling House of Night series, Zoey has returned, mostly whole, from the Otherworld to her rightful place as High Priestess at the House of Night. Her friends are just glad to have her back, but after losing her human consort, Heath, will Zoey - or her relationship with her super-hot Warrior, Stark - ever be the same? Stevie Rae is drawn even closer to Rephaim, the Raven Mocker with whom she shares a mysterious and powerful Imprint, but he is a dangerous secret that isolates her from her school, her red fledglings, and even her best friends. When the dark threat of Neferet - who is coming closer and closer to achieving her twisted goal of immortality - and Kalona returns, what will it take to keep the House of Night from being lost forever, and what will one desperate girl do to keep her heart from being irreparably broken?
Last one is planned to release on January 2011
