When I wrote Tales of the Dim Knight with my wife Andrea, it was originally intended as a one-shot novel.

In fact, when I wrote the original ending, it tied everything up nicely in a big bow that precluded the possibility of sequels and that ending was in the book until the last edits to the story in mid-to-late 2010.

However, as my wife and I talked about it, it became clear that the ending really was a problem. It a little too pat and a little too clunky and it really closed the door to any possibility of a sequel. It literally took the Johnson family two years down the road from after the end of the book with final conclusions for Marco, Leona Campbell, and all our other characters. It was almost too neat and too pat. So, we decided to end strong and leave the possibility of a sequel in place at the same time. There were a couple of things that made the Powerhouse sequels seem like a good project late Spring of this year.

From a marketing perspective, the big advice that I'd been reading is that series are the best way to go. In addition, I'd been getting good reaction, if I wasn't getting the volume of reaction that I'd hoped for. I thought if I could get a series together, this character might take off.

Second, I really have been watching more superhero stories and realize there's a lot more we can do. There are more things we can poke fun at. I thought we did a pretty exhaustive work in the first book. We covered superhero team ups, Captain America, Batman, heck even Underdog, but I think there was more to do.

Third, I think there's a lot more we can get out of these characters, so it made sense to write the sequels and I'm enjoying the process immensely.
