Buffy takes a job for a corporate security company which is run by Kennedy. It's all employed by the Slayers Buffy was once in charge of. Her taking the job is all a means of trying to get her life together (in the previous graphic novel she had been working at a coffee shop). They are hired by a computer nerd who says an organization from a hell dimension is trying to kill him. The organization? It's Wolfram & Hart. After this adventure--and a tentacled monster--is resolved, Buffy is confirmed that this type of work is not for her. She's the Slayer and that's what she has to do.
The second half of the book is "Billy the Vampire Slayer", about a gay teenager who wants to be a slayer. He's encouraged by his blonde haired blue-eyed friend, Devon. Together, they help fight the zompires that are taking over their town. While this is an interesting twist to the book, having a male slayer, I felt too much time was taken with this character, though they eventually meet up with Buffy at the end.
I have the same feeling about this as I did volume 2--that it's just "okay". I don't think I'll be picking up any future volumes.
