i'v seen the movies and loved them, but i havent read the books.
Out of the Madhouse
By Christopher Golden
Sunnydale is being besieged by dark forces. But even with Buffy providing her unique style of damage control, it's more than one Slayer can handle - especially since the abominations are coming from a centuries-old portal through time and space.
