Time to go to Hell… Literally. It’s been a year since the Dark One has been vanquished. So how is it that contraband is being smuggled into the Nine Realms from the Netherverse? The Dark One isn’t a threat anymore. Or is he? When the Angels discover Black Melody on Earth – a substance so potent it can transform peaceful beings into murderous monsters – they realize the threat from the Netherverse isn’t over. What’s more? A strange entity has descended from the stars above, demanding to speak to the Dark One. If this strange and powerful creature doesn’t get her way, she threatens to destroy the Nine Realms by raising the dead. Can you say Zombie Apocalypse, anyone? The Dark Gate Angels must undergo their most dangerous mission ever. Get into Hell, find the Dark One and get him to stop this new threat. But how do you negotiate with evil?
