DC vs. Vampires, all-out war

"One of the last secret, underground human cities is facing total annihilation and its leader--John Constantine--must plan a suicide mission to assassinate a key lieutenant in the vampire empire! The survivors of a horrifying vampire attack, led by Deathstroke, take shelter with Talia al Ghul. With intel from a hero recently saved from vampirism, John Constantine prepares them for a (suicide) mission, while Midnighter goes through every scenario in his head and finds out the dark truth.

Meanwhile the mysterious vampire Lord Cinder has become aware of their plans and prepares a surprise."-- Provided by publisher.
