Kate Daniels - Dramatized Adaptation

The world has suffered a magic apocalypse. It comes in waves, without warning, and vanishes as suddenly as it appears. When magic is up, planes drop out of the sky, cars stall, and electricity dies. When magic is down, guns work and spells fail.

Magic waves feed on technology, gnawing down skyscrapers to skeletal husks. Monsters prowl the ruined streets, shapeshifters stalk their prey; and the Masters of the Dead, necromancers driven by their thirst of knowledge and wealth, pilot blood-crazed vampires with their minds.

In this world lives Kate Daniels. Kate likes her sword a little too much and has a hard time controlling her mouth. The magic in her blood makes her a target, and she spent most of her life hiding in plain sight.  But sometimes even trained killers make friends and fall in love, and when the universe tries to kick them in the face, they kick back.
