When the dead refuse to stay buried, London trembles.

Rob Cromwell and Julian Blackwood thought they’d found their place in London’s supernatural shadow world. But when a ghost from Julian’s past returns with murder on his mind, their hard-won peace shatters like glass.

Mitch Longfield should be dead—Julian killed him four years ago. Yet here he stands, more dangerous than ever, weaving chaos magic and ready to burn London to ash to claim what he seeks.

As vampires clash in blood-soaked battles and werewolf dynasties sharpen their claws for war, Fiona Kendall discovers the Red Sisters aren't the benevolent teachers they claim to be. Trapped in a nightmare realm, she must embrace powers she barely understands—or become the key to unleashing an imprisoned horror upon the world.

From the vampire tunnels beneath the city to the ghostlit streets above, and secret bases hidden under Russell Square, the shadow war has begun. Ancient enemies are stirring. The dead are rising. And at the heart of it all lurks something that was chained away in the hope it would never return.

Some prisons were built to last forever. Tonight, the locks are breaking.

Perfect for fans of Ben Aaronovitch's Rivers of London and Jim Butcher's Dresden Files, The Mortal Edge delivers pulse-pounding action, dark magic, and characters you'll fight alongside until the very last page.
