Title: "Speed"
Author: Cherie Bennett & Jeff Gottesfeld

Summary: (from the back of the book) Clark and his friends are preparing for the Multicultural Day celebration in Smallville. As the festival approaches, several racially motivated attacks take place. Flyers for the festival are burned, a friend's house is trashed, and a runaway oil truck narrowly misses another friend's home. Oddly, the violence occurs in super-fast hyper-time, so quickly that no one can see the attacker. When Clark realizes he's the only one who can solve the mystery, he tries to confront the culprit in "frozen time" to derail the ultimate racist plot.
