A synopsis of the book, along with the date each chapter began online:
Chapter 17: Kiki's Virus
Kiki's Virus (1/1/00): There really is a Y2K bug. And it's not a computer glitch. Every human (except one) that has come in contact with Kiki goes into a coma.
The Quatrix (1/22/00): A cool take-off on The Matrix. Dr. Schlock tries to find out about the experiments done by Dr. Crabtree to Kiki to reverse the effects of the virus.
Tuffy (1/31/00): Schlock figures out how to stop the virus, with a little prodding by Sam.
Chapter 18: Love Potion
Squeekybobo Ball! (2/21/00): The Dimension of Pain has a new sport... but watch out for that Flower Breathing Dragon. How evil.
The Love Potion: Part 1 (3/6/00): Gwynn uses a love potion to get Dex to fall for Zoe, so Zoe won't be mad at her for still using magic powers. Gwynn then tries to get Riff to get back together with her by using the potion, but everything goes horribly wrong.
Sluggy Freelance, Where Are You? (3/27/00): The Sluggy gang gets kidnapped. Guest appearances from GPF, Bruno the Bandit, Nukees, and Kevin and Kell. Scooby Doo parody.
