Pop culture, chaos theory, and matters of the heart collide in this unique novella from the Hugo and Nebula Award-winning author of Doomsday Book.

Sandra Foster studies fads–from Barbie dolls to the grunge look–how they start and what they mean, for the HiTek corporation. Bennett O'Reilly studies monkey-group behavior and chaos theory for the same company. When the two are thrust together due to a misdelivered package and a run of seemingly bad luck, they find a joint project in a flock of sheep. What better animal to study both chaos theory and the herd mentality that so often characterizes human behavior? Unfortunately, Sandra and Bennett must endure a series of setbacks, heartbreaks, dead ends, and disasters before they are able to find answers to their questions–with the unintended help of the errant, forgetful, and careless office assistant Flip.
