Stun-Man: The Masters stories 2

This is basically the second book of Jack except, its not about him. Its about his son Sam. In this book, Sam finds out what he really is and what he can do. He has to help Don fight two enemies as well as get over the most saddest moment in his life. This will be a very short book since most of the story is in the second book of Stun-Man. Sorry if I take the names of other people you may know or that you are. Any characters that are similar to another book or movie is completely coincidental. I was in a rush with the names. Thank you.
