The viewpoint of Christoff is a short story based on a character in the Paul Smith series. It takes place after the events of the first book, Person of Interest, and during the events of the second book, still coming.
It will obviously contain spoilers from the first book and some teases from what's to come in the second book. This short story, or any other short story, does not contain any need to know information in order to read the main series.
The primary purpose of the short stories is for the readers who like the story to support me and motivate me to continue writing. The secondary purpose is to give readers more depth to the story, characters and universe, and to tell stories that would never have reached the book, like the story of Ferdi Smith.
