Things had settled down after the incident with the brothers and time folding. Years had passed and there wasn’t a word from the Alphas or Miguel and Diego. James personally supervised the refitting of both Antarctica stations. Their emphasis would now be solely focused on time anomalies. He didn’t want to be caught off guard again. Adriana had developed a company of highly skilled agents, and he could not be prouder of her performance. She would one day inherit the job, and he was confident she would be wonderful at it. Things were running smoothly, too smoothly. The fact of the matter was that the Archivist was bored. Then an alert came in from his stationmaster Moriarty. Someone was knocking at the door and it was a butler. The world was about to change. It has been seven years since James Aranas became the Archivist. He has not spoken with the McGonegals or anyone else outside of the agency who was involved in defeating the monster Atun. All of that was about to change because all of his friends were also visited by the butler. Angular Frequency is the conclusion of the McGonegal Chronicles series and as with anything involving the McGonegals, it is complicated and deadly. All his friends have settled back into their lives, but now retirement is over. Now the world once again requires their services and that includes the Alphas. The threat is even graver than before. The question is are they still up to the challenge? Time waits for no one, and she is a cruel taskmaster. The threat is at their doorsteps, and it is announced by a figure in a morning suit.
