Free the Dark by Nicola Rose

The world is descending into devastating chaos. There’s a new enemy to mankind on the horizon… it’s me.
I’m ready to let go of morality. It’s time to play.
But how much ‘fun’ is too much when you’ve accidentally triggered the vampire apocalypse?! Are there any lines left that shouldn’t be crossed?
There’s a brand new hunger under my skin, and it wants more,/i>. More of Alex’s darkness, more of Zac’s light—
The two don’t go together, but that doesn’t stop the pull in my chest, or the ravenous shadowy beat that strikes a constant melody in my soul, driving me forward, destruction in my wake.
Can I really side with vampires and stand by as humanity is lost?
Because once that darkness is set free, pulling it back might be beyond my capabilities.
