The Evil That Men Do (Buffy novel)

After a vicious shooting spree by Brian Dellasandro, a straight A student, the town of Sunnydale goes into a state of shock, though not one everyone would expect; they turn on each other and become nasty. At the same time, Helen, an ancient vicious vampire over 1500 years old, has come to Sunnydale. She has hunted and killed every single Slayer she has ever met in her life, and Buffy is next on her list. Helen and her lover, Julian, have come to Sunnydale to raise Meter, a goddess of destruction, and to do that they need the heart of the Slayer and the ashes of the Emperor Caligula from way back when in 47 A.D. The urn, containing his ashes, has arrived in Joyce's gallery, and is later stolen. After a run-in with Helen, Buffy learns that Angelus and Helen used to be paramours in the 19th century, but that it ended when he regained his soul. Angel explains to her about Helen's past and how she came to hunt down Slayers.

Buffy and her friends are captured and suited up on the night of Meter's ascension. They are led onto a battleground where Buffy must stay alive against dozens of opponents as well as her friends who have been infected by the Potion of Madness in order to prevent Meter from rising.

The book was originally supposed to be released in July 1999, but was postponed due to the Columbine High School massacre. The Columbine incident also influenced the airings of the episodes "Earshot" and "Graduation Day, Part Two".
