I, Vampire. Volume 1 Tainted love - Joshua Hale Fialkov

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! Their past behind them, they find themselves ready to battle to the death...but only if those feelings really are all gone.
