    The Earth’s growing population has finally been controlled, with lifespans limited to eighty years. Except for those who choose to become a commune—five minds sharing one body, living for four hours at a time, but combined a lifespan of nearly 150 years.

    Alex, Kate, Sierra, Ben, and Mike have already spent 25 years together as a commune. Together, they go to a Death Park where games are played in which extra lifespan can be gambled like money. They try to win time to upgrade their next host body, but then Kate accepts a dangerous offer, and one of them disappears.

    Someone is trying to kill off members of the commune. But is it one of them, or is someone else playing a deadly game?

    Grey doesn’t believe Elora just vanished into thin air, and that nobody in a town full of psychics knows what happened. But as she starts to dig into the issue, she begins to realize everybody in town is hiding something. Even her grandmother Honey, her childhood crush Hart, and her late mother.

    When suddenly a mysterious boy emerges from the bayou with links to Elora and the town’s bloody history, Grey realizes that the town’s past is far more present and dangerous than she’d ever understood.

      Pubdate: 14th of September
      Publisher: Harper Voyager

      I am totally beyond excited about this. I’ve only discovered Jay Kristoff’s books last year, but I just love his style of writing. And I just can’t see how this one can disappoint. I mean… dark and nasty vampires? Yes, please!

      The creatures of the night have walked the day without fear for almost three decades. How? Well, the sun hasn’t come up in twenty-seven years. Humanity fought the cold blood legions once, but now they exist only in some scattered settlements. Gabriel de León is the last of the Silversaints, which is a holy order dedicated to defending the realm and church. He’s imprisoned for the murder of the vampiric king. The charge? Telling the story of his life.

      It’s a tale of years, from his youth in the monastery of San Michon, to the forbidden love that spelled his undoing, and the betrayal that saw his order annihilated. And Gabriel tells the most important story of all: the Grail, a legendary cup that would bring an end to the eternal night. But the location is only known by a teenage urchin named Dior.

      Dior and Gabriel forge an unbreakable bond, on a road to redemption. That is, until the Grail shattered. With the cup destroyed, and the last Silversaint awaiting execution, how can this undying empire come to an end?

Citizeness Savine, on the other hand, needs to turn her talent from profit to survival to claw her way to redemption. Then there’s Orso, who is now the lowest of the low: a monarch. And in the bloody North, Rikke and her Protectorate are running out of allies, while Black Calder gathers his forces and plots revenge.

However, Zetian is not planning on missing an opportunity to leverage their combined might and infamy to survive attempt after attempt on her life, until she can figure out exactly why the pilot system works in its misogynist way—and stop more girls from being sacrificed.

But then, in a donut shop, Shizuka meets Lan Tran, a retired starship captian, interstellar refugee, and mother of four.
