Straight from the pages of Justice League Dark comes John Constantine! Problem is, rather than help Andrew in his war against the Queen of Blood, Constantine figures it would make more sense to just wipe out all of the vampires, including Andrew!

For hundreds of years, vampire Andrew Stanton kept mankind safe from the horrors of the supernatural world, thanks to a truce he made with his ex-lover Mary, the Queen of the Damned. But now that truce has reached a bloody end and Andrew must do everything in his power to stop Mary and her dark forces from going on a killing spree -- and she plans to start with the heroes of the DCU!

Mary and Professor Troughton meet up with Andrew's oldest friend, Deborah Dancer, to learn more about his past - and to hatch a plan that might save Andrew from his curse! Trouble is, they're going to have to track down the deadliest vampire alive to do it... What is Andrew planning for the future of the vampire race?
