This Halloween will awaken the beast inside.

This year's Moon Awakening is the one Ari has been waiting for her whole life. All the freshly-turned sixteen year olds will be ushered into the Lunar Falls pack as full members, either joining the hunt that will trigger their gene for the first time or Presenting on Halloween night. And this year-her year-the Moon Awakening will fall on a full moon, like it was all meant to be...

Except Ari isn't a werewolf.

Not being of the Blood had never bothered her before, but now that it's her sixteenth birthday, the constant reminders that she's the adopted human of the Lunar Falls pack has her feeling like she's losing her two best friends, not to mention her family.

Halloween is as frightful and exciting as ever, but when the Moon Awakening turns lethal and a friend disappears, there's more than just Ari's feelings in play. And when Dean, the guy she's been crushing on forever, agrees to help her find her lost friend the stakes get even higher.

As a mysterious Djinn man interferes with premonitions and vague warnings, Ari must claw out a place for herself in a world she doesn't belong-and become something more.

With something new awakened inside her, Ari fights to find her place and save her friends. But are her new abilities worth the cost? And will her friends and family-and Dean-accept her now that she's not just the human among them?
