When darkness comes, it doesn't ask permission.
Paramedic Lucy Barker thinks she's seen it all, after years of responding to violent accidents and medical emergencies on the streets of York. But when she arrives on the scene of a brutal attack, Lucy finds herself drawn into a nightmare world beyond her comprehension.
Inside a blood-drenched room lay two bodies; one dying from a neck wound, the other with a stake through the heart. Standing over both, a creature torn from the pages of myth: Adam, a vampire with two and a half centuries of terror in his past.
And he's not the only one.
Dark and terrifying secrets wait for Lucy in the gloaming, and one thing is clear - it will take all her strength and cunning to survive the coming storm when Darkness Comes Alive.
