THIS IS NOT A WARNING.

A gruesome ritual murder has stained the Oxfordshire countryside. This is just the first incident in a chain of events awakening Detective Inspector Joel Solomon to his worst nightmare - and a dreadful omen of things to come. Because Joel has a secret: He believes in vampires.

Alex Bishop is an agent of the Vampire Intelligence Agency. She's tasked with enforcing the laws of the global Vampire Federation, and hunting rogue members of her race. A touch job made tougher when the Federation comes under attack by traditionalist vampires. They have a stake in old-school terror - and in an uprising as violent as it is widespread.

Now it's plunging Alex and Joel into a deadly war between the living and the un-living - and against a horrifying tradition given new life by the blood of the innocent.
