Book Four of the science fiction space opera series, The Revelation of Brian A. Pearlmitter, takes the story in an entirely new - and entirely unexpected - direction. While this book covers only 5 days in the life of Roger, Bess, Jane and the other members of the Connection, it serves as both an ending and a beginning, not only the story, but for each of the main characters as well. When the alien that calls himself Brian A. Pearlmitter reveals the design of the device that the team must build, they realize that they have to dedicate their remaining time to the singular purpose of creating something so difficult and dangerous, that it could cost one of the team members their life. They realize that their time of discovering the wonders of the Revelation is over. Soon, they must begin the task of actually fulfilling their purpose on earth. They know it won't be easy, but even though there may be danger, they feel a shared sense of optimism; finally, they know their purpose and have faith that they will be able to accomplish it. They are eager to get started on what comes next. But other things are happening, unknown to anyone in the group. There is an evil thing in their inner circle and none of them are aware of it. Book Four: The Celebration provides the most shocking and the most unexpected events of the entire story arc.
