That’s one option I’ve considered. I’ve also played around a bit with the Protagonist being Luke while making Boone the Guardian and the IC and the Contagonist becomes the MC. Then, the MC and the IC are kinda like playing chess with Luke as a chess piece. That’s interesting, but it is a radical departure and might be too experimental to get the publishing houses interests in a new author.
1.) In the overall series of books, there are more than just the one bad guy. Hela (Loki’s daughter, not to be confused with Marvel’s Hel) is another bad guy. Anyway, Hela sends the undead to Luke’s home with the intent to destroy him. She won’t be revealed for another few novels, but she rules over the land of the dead. She has not and will not incarnate. But, I don’t really have an explanation, yet, for the serendipity of Boone & Co and her undead arriving at near the same time.
2.) Luke has always known. Here it is revealed to other characters and to the reader.
3.) My recent statement about what is in the book focused on Luke, specifically. As such, it didn’t discuss Boone’s stuff. That was deliberate.
4.) To have his college admission and free-ride taken away so that he is “forced” to stay home to take care of his step-dad.
